                                   CORPORATION

                     CHANGE-IN-CONTROL EMPLOYMENT AGREEMENT

      THIS AGREEMENT dated as of June 1, 2001 (the "Agreement Date") is made by
and among Exelon Corporation, incorporated under the laws of the Commonwealth of
Pennsylvania (together with successors thereto, the "Company"),
_____________________, a _______________ corporation (together with successors
thereto, the "Subsidiary"), and _____________________ ("Executive").

                                    RECITALS

      The Board of Directors of the Company (the "Board") has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued services of the Executive, despite the
possibility or occurrence of a Change in Control of the Company. The Board
believes it is imperative to reduce the distraction of the Executive that would
result from the personal uncertainties caused by a pending or threatened Change
in Control or a Significant Acquisition, to encourage the Executive's full
attention and dedication to the Company, and to provide the Executive with
compensation and benefits arrangements upon a Change in Control which are
competitive with those of similarly-situated corporations. This Agreement is
intended to accomplish these objectives.

                                   ARTICLE I.

                                   DEFINITIONS

      As used in this Agreement, the terms specified below shall have the
following meanings:

      1.1 "Accrued Annual Incentive" means the amount of any Annual Incentive
earned but not yet paid with respect to the Company's latest fiscal year ended
prior to the Termination Date.

      1.2 "Accrued Base Salary" means the amount of Executive's Base Salary that
is accrued but not yet paid as of the Termination Date.

      1.3 "Accrued LTIP Award" means the amount of any LTIP Award earned and
vested, but either deferred or not yet paid as of the Termination Date.

      1.4 "Accrued Obligations" means, as of any date, the sum of Executive's
Accrued Base Salary, Accrued Annual Incentive, Accrued LTIP Award, any accrued
but unpaid paid time off, and any other amounts and benefits which are then due
to be paid or provided to Executive by the Company, but have not yet been paid
or provided (as applicable).

      1.5 "Affiliate" means any Person (including the Subsidiary) that directly
or indirectly controls, is controlled by, or is under common control with, the
Company. For purposes of this definition the term "control" with respect to any

<PAGE>
direction of management or policies of such Person, directly or indirectly,
whether through the ownership of Voting Securities, by contract or otherwise.

      1.6 "Agreement Date" -- see the introductory paragraph of this Agreement.

      1.7 "Agreement Term" means the period commencing on the Agreement Date and
ending on the second anniversary of the Agreement Date or, if later, such later
date to which the Agreement Term is extended under the following sentence,
unless earlier terminated as provided herein. Commencing on the first
anniversary of the Agreement Date, the Agreement Term shall automatically be
extended each day by one day to create a new two-year term until, at any time
after the first anniversary of the Agreement Date, the Company delivers written
notice (an "Expiration Notice") to Executive that the Agreement shall expire on
a date specified in the Expiration Notice (the "Expiration Date") that is not
less than 12 months after the date the Expiration Notice is delivered to
Executive; provided, however, that if a Change Date, Imminent Control Change,
Disaggregation or Significant Acquisition occurs before the Expiration Date
specified in the Expiration Notice, then such Expiration Notice shall be void
and of no further effect. If such Imminent Control Change or Disaggregation does
not culminate in a Change Date, then such Expiration Notice shall be reinstated
and the Agreement shall expire on the date originally specified as the
Expiration Date, or if later, the date the Imminent Control Change lapses or the
end of the sixtieth day after the Disaggregation. Notwithstanding anything
herein to the contrary, the Agreement Term shall end at the end of the Severance
Period if applicable, or if there is no Severance Period, the earliest of the
following: (a) the second anniversary of the Change Date, (b) eighteen (18)
months after the Significant Acquisition, provided there has been no Change
Date, (c) the end of the sixtieth day after the Disaggregation if there has been
no Change Date after the Disaggregation, or (d) the Termination Date.

      1.8 "Annual Incentive" -- see Section 2.8.

      1.9 "Applicable Trigger Date" means

      Post-Significant Acquisition Period; and

      representing 20% or more of the combined voting power of all the then
      outstanding Voting Securities of Company (such an SEC Person, a "20%
      Owner"); provided, however, that for purposes of this subsection (a), the
      following acquisitions shall not constitute a Change in Control: (1) any
      acquisition directly from the Company (excluding any acquisition resulting
      from the exercise of an exercise, conversion or exchange privilege unless
      the security being so exercised, converted or exchanged was acquired
      directly from the Company), (2) any acquisition by the Company, (3) any
      acquisition by an employee benefit plan (or related trust) sponsored or

      becomes a 20% Owner by reason of an acquisition by the Company, and such
      20% Owner of the Company shall, after such acquisition by the Company,
      become the beneficial owner of any additional outstanding common shares of
      the Company or any additional outstanding Voting Securities of the Company
      (other than pursuant to any dividend reinvestment plan or arrangement
      maintained by the Company) and such beneficial ownership is publicly
      announced, such additional beneficial ownership shall constitute a Change
      in Control; or

            (b) Individuals who, as of the date hereof, constitute the Board
      (the "Incumbent Board") cease for any reason to constitute at least a
      majority of the Incumbent Board; provided, however, that any individual
      becoming a director subsequent to the date hereof whose election, or
      nomination for election by the Company's shareholders, was approved by a
      vote of at least a majority of the directors then comprising the Incumbent
      Board shall be considered as though such individual were a member of the
      Incumbent Board, but excluding, for this purpose, any such individual
      whose initial assumption of office occurs as a result of an actual or
      threatened election contest (as such terms are used in Rule 14a-11

      resulting in the continued utilization of such assets (or the operating
      products of such assets) by the Company (such reorganization, merger,
      consolidation, sale or other disposition, a "Corporate Transaction");
      excluding, however, a Corporate Transaction pursuant to which:

                  (i) all or substantially all of the individuals and entities
            who are the Beneficial Owners, respectively, of the outstanding
            common stock of Company and outstanding Voting Securities of the
            Company immediately prior to such Corporate Transaction beneficially
            own, directly or indirectly, more than 60% of, respectively, the
            then-outstanding shares of common stock and the combined voting
            power of the then-outstanding voting securities entitled to vote
            generally in the election of directors, as the case may be, of the
            corporation resulting from such Corporate Transaction (including,
            without limitation, a corporation which, as a result of such
            transaction, owns the Company or all or substantially all of the
            assets of the Company either directly or through one or more
            subsidiaries) in substantially the same proportions as their
            ownership immediately prior to such Corporate Transaction of the
            outstanding common stock of Company and outstanding Voting
            Securities of the Company, as the case may be;

                  (ii) no SEC Person (other than the corporation resulting from
            such Corporate Transaction, and any Person which beneficially owned,
            immediately prior to such corporate Transaction, directly or
            indirectly, 20% or more of the outstanding common stock of the
            Company or the outstanding Voting Securities of the Company, as the
            case may be) becomes a 20% Owner, directly or indirectly, of the
            then-outstanding common stock of the corporation resulting from such
            Corporate Transaction or the combined voting power of the
            outstanding voting securities of such corporation; and

                  (iii) individuals who were members of the Incumbent Board will
            constitute at least a majority of the members of the board of

      such 30th day shall be deemed to be the "Disability Effective Date")
      unless, before such 30th day, Executive shall have resumed the full-time
      performance of Executive's duties.

            (b) "Disability" means any medically determinable physical or mental
      impairment that has lasted for a continuous period of not less than six
      months and can be expected to be permanent or of indefinite duration, and
      that renders Executive unable to perform the duties required under this
      Agreement.

      3.2 Death. Executive's employment shall terminate automatically upon
Executive's death during the Agreement Term.

      3.3 Termination by the Company for Cause.

            (a) Termination for Cause During the Current Post-Merger Period,
      Post-Change Period, and Post-Disaggregation Period. During the Current
      Post-Merger Period and the Post-Change Period, the Company may terminate
      Executive's employment (or cause Executive's employment to be terminated)
      for Cause solely in accordance with all of the substantive and procedural
      provisions of this Section 3.3(a).

                  (i) Definition of Cause. For a Termination of Employment for
            Cause for which the Notice of Termination is given during the
            Current Post-Merger Period, the Post-Change Period or the
            Post-Disaggregation Period, "Cause" means any one or more of the
            following:

                        (1) the Executive's willful commission of acts or
                  omissions which have, have had, or are likely to have a
                  material adverse effect on the business, operations, financial
                  condition or reputation of the Company or an Affiliate;

                        (2) the Executive's conviction (including a plea of
                  guilty or nolo contendere) of a felony or any crime of fraud,
                  theft, dishonesty or moral turpitude; or

                        (3) the Executive's material violation of any statutory
                  or common-law duty of loyalty to the Company or an Affiliate.

                  For purposes of this Section, no act, or failure to act, on
            the part of the Executive shall be considered "willful" unless it is
            done, or omitted to be done, by the Executive in bad faith or
            without reasonable belief that the Executive's action or omission
            was in the best interests of the Company. Any act, or failure to
            act, based upon authority given pursuant to a resolution duly
            adopted by the Board or


                                       17

            officer of the Company other than Executive or based upon the advice
            of counsel for the Company shall be conclusively presumed to be
            done, or omitted to be done, by the Executive in good faith and in
            the best interests of the Company.

                  (ii) Procedural Requirements for Termination for Cause. The
            Executive's Termination of Employment shall not be deemed to be for
            Cause under this Section 3.3(a) unless and until there shall have
            been delivered to the Executive a copy of a resolution duly adopted
            by the affirmative vote of not less than 60% of the entire
            membership of the Board at a meeting of such Board called and held
            for such purpose (after reasonable written notice of such meeting is
            provided to the Executive and the Executive is given an opportunity,
            together with counsel, to be heard before the Board), finding that,
            in the good faith opinion of the Board, the Executive's acts, or
            failure to act, constitutes Cause and specifying the particulars
            thereof in detail.

                  (iii) Post-Disaggregation Period. In the event Executive's
            Termination of Employment is from a Disaggregated Entity in a
            Post-Disaggregation Period, the definition of Cause and the
            procedural requirements for termination for Cause in this Section
            3.3(a) shall be applied by substituting "Disaggregated Entity" for
            "Company," "affiliate of the Disaggregated Entity" for "Affiliate,"
            and "Disaggregated Entity's Board" for "Board." Further, the Company
            shall have no obligation to provide payments or benefits under
            Section 4.3 if the Board determines that the Company could have
            terminated Executive's employment for Cause as defined above in
            Section 3.3(a)(i)(1), if the Executive had been employed by the
            Company, such determination by the Board to be made as provided in
            Section 3.3(a)(ii) but applying the flush language at the end of
            Section 3.3(a)(i) by substituting "Disaggregated Entity" for
            "Company" and "Disaggregated Entity's Board" for "Board."

            (b) Termination for Cause During the Imminent Control Change Period
      or Post-Significant Acquisition Period. During the Imminent Control Change
      Period and any Post-Significant Acquisition Period, the Company may
      terminate Executive's employment (or cause Executive's employment to be
      terminated) for Cause solely in accordance with all of the substantive and
      procedural provisions of this Section 3.3(b).

                  (i) Definition of Cause. For a Termination of Employment for
            Cause for which the Notice of Termination is given during the
            Imminent Control Change Period or Post-Significant Acquisition
            Period, "Cause" means any one or more of the following:

                        (1) the Executive's willful commission of acts or
                  omissions which have, have had, or are likely to have a
                  material adverse effect on the business, operations, financial
                  condition or reputation of the Company or an Affiliate;


                                       18
<PAGE>
                        (2) the Executive's conviction (including a plea of
                  guilty or nolo contendere) of a felony or any crime of fraud,
                  theft, dishonesty or moral turpitude;

                        (3) the Executive's material violation of any statutory
                  or common law duty of loyalty to the Company or an Affiliate;
                  or

                        (4) Executive's failure to meet objective performance
                  criteria of the position, provided that, in the case of a
                  Termination of Employment during an Imminent Control Change
                  Period (other than after a Disaggregation) this Section
                  3.3(b)(i)(4) shall be inapplicable if the Imminent Change in
                  Control culminates in a Change Date.

                  For purposes of this Section, no act, or failure to act, on
            the part of the Executive shall be considered "willful" unless it is
            done, or omitted to be done, by the Executive in bad faith or
            without reasonable belief that the Executive's action or omission
            was in the best interests of the Company. Any act, or failure to
            act, based upon authority given pursuant to a resolution duly
            adopted by the Board or upon the instructions of the chief executive
            officer or a senior officer of the Company other than Executive or
            based upon the advice of counsel for the Company shall be
            conclusively presumed to be done, or omitted to be done, by the
            Executive in good faith and in the best interests of the Company.

                  (ii) Procedural Requirements for Termination for Cause. The
            Executive's Termination of Employment shall not be deemed to be for
            Cause under this Section 3.3(b) unless and until there shall have
            been delivered to the Executive a copy of a resolution duly adopted
            by the affirmative vote of not less than a majority of the entire
            membership of the Board, finding that the Executive's acts or
            failure to act, constitute Cause and specifying the particulars
            thereof in detail. Executive shall receive advance notice of such
            vote of the Board, but shall not have the right to appear in person
            or by counsel before the Board.

      3.4 Termination by the Executive for Good Reason. During the Current
Post-Merger Period, the Post-Change Period, an Imminent Control Change Period, a
Post-Significant Acquisition Period or Post-Disaggregation Period, Executive may
terminate his or her employment for Good Reason in accordance with the
substantive and procedural provisions of this Section 3.4.

            (a) Definition of Good Reason. For purposes of this Section 3.4(a),
      and subject to the provisions of subsections (b) through (f), "Good
      Reason" means the occurrence of any one or more of the following actions
      or omissions prior to the Termination Date during the Current Post-Merger
      Period, the Post-Change Period, the Imminent Control Change Period, the
      Post-Significant Acquisition Period or the Post-Disaggregation Period:

                  (i) a material adverse reduction in the nature or scope of the
            Executive's office, position, duties, functions, responsibilities or
            authority (other than in a Post-Significant Acquisition Period);

                  (ii) a material reduction of the Executive's salary, incentive
            compensation or aggregate benefits unless such reduction is part of
            a policy, program or arrangement applicable to peer executives of
            the Company and of any successor entity;

                  (iii) the failure of any successor to the Company to assume
            this Agreement;

                  (iv) a relocation (other than in a Post-Significant
            Acquisition Period), of more than 50 miles of (i) the Executive's
            workplace, or (ii) the principal offices of the Company or its
            successor (if such offices are the Executive's workplace), in each
            case without the consent of the Executive; provided, however, in
            both cases of (i) and (ii) of this Section 3.4(a), such new location
            is farther from Executive's residence that the prior location;

                  (v) a requirement (other than in a Post-Significant
            Acquisition Period) of the greater of (i) more than 24 days of
            travel per year, or (ii) at least 20% more business travel than was
            required of the Executive prior to the Applicable Trigger Date;

                  (vi) any failure by the Company to comply with any of the
            provisions of Sections 2.7, 2.8 and 2.9 of this Agreement, other
            than an isolated, insubstantial and inadvertent failure not
            occurring in bad faith and which is remedied by the Company promptly
            after receipt of notice thereof given by the Executive; or

                  (vii) a material breach of this Agreement by the Company or
            its successor;

      provided that the occurrence of a Disaggregation shall not be Good Reason
      if the Executive retains substantially the same position (determined
      without regard to reporting requirements) with the Disaggregated Entity,
      with substantially the same compensation and benefits in the aggregate, as
      immediately prior to such Disaggregation, notwithstanding Sections
      3.4(a)(i), 3.4(a)(ii) and 3.4(a)(vi).

            (b) Additional Basis for Good Reason During the Current Post-Merger
      Period. With respect to the Current Post-Merger Period, "Good Reason"
      shall have the meaning set forth in Section 3.4(a) and shall also include
      any of the following which occurred prior to the Agreement Date:

                  (i) a material adverse alteration in the nature or scope of
            the Executive's position, duties, functions, responsibilities or
            authority;


                                       20
<PAGE>
                  (ii) a determination by the Executive, made in good faith
            during the term of the Executive's change in control employment
            agreement dated as of [UNICOM: SEPTEMBER __, 1999; PECO:
            _________________] and prior to the Agreement Date, that, as a
            result of the change in control resulting in the merger of Unicom
            Corporation and PECO Energy Corporation, the Executive is
            substantially unable to perform, or that there has been a material
            reduction in, any of the Executive's duties, functions,
            responsibilities or authority;

                  (iii) a relocation of more than 50 miles of the Executive's
            workplace, without the consent of the Executive;

                  (iv) a requirement of at least 20% more business travel than
            was required of the Executive prior to the change in control
            resulting in the merger of Unicom Corporation and PECO Energy
            Corporation.

            (c) Application of "Good Reason" Definition During the Imminent
      Control Change Period. During the Imminent Control Change Period, "Good
      Reason" shall not include the events or conditions described in Section
      3.4(a)(i), 3.4(a)(iv) or 3.4(a)(v) unless the Imminent Control Change
      Period culminates in a Change Date. Further, if Executive's Termination of
      Employment occurs during an Imminent Control Change Period that culminates
      in a Change Date, then, except as provided in Section 3.4(d), the
      definition of "Good Reason" shall be applied as though Sections 2.2, 2.7,
      2.8, and 2.9 were applicable during the Imminent Control Change Period
      prior to the Executive's Termination of Employment.

            (d) Special Conditions Relating to Good Reason During the
      Post-Disaggregation Period. If Executive retains substantially the same
      position with the Disaggregated Entity as immediately prior to the
      Disaggregation (determined without regard to reporting requirements), then
      (1) Section 3.4(a)(i) shall apply only with respect to the Executive's
      office, duties, functions, responsibilities or authority as in effect at
      the Disaggregated Entity on the day following the Disaggregation, (2)
      subsections 3.4(a)(iv) and 3.4(a)(v) shall apply only with respect to
      relocations or travel required more than 60 days after the Disaggregation
      and shall be applied by substituting "Disaggregated Entity" for "any
      successor to the Company", and (3) all references in Section 3.4 to the
      Company or its successor shall be to the Disaggregated Entity or its
      successor.

            (e) Limitations on Good Reason. Notwithstanding the foregoing
      provisions of this Section 3.4, no act or omission shall constitute a
      material breach of this Agreement by the Company, nor grounds for "Good
      Reason":

                  (i) unless the Executive gives the Company and the Employer 30
            days' prior notice of such act or omission and the Company fails to
            cure such act or omission within the 30-day period;

                  (ii) if the Executive first acquired knowledge of such act or
            omission more than 12 months before the Executive gives the Company
            and the Employer such notice; or


                                       21
<PAGE>
                  (iii) if the Executive has consented in writing to such act or
            omission in a document that makes specific reference to this
            Section.

            (f) Notice by Executive. In the event of any Termination of
      Employment by Executive for Good Reason, Executive shall as soon as
      practicable thereafter notify the Company and the Employer (and
      Disaggregated Entity, if applicable) of the events constituting such Good
      Reason by a Notice of Termination. Subject to the limitations in Section
      3.4(e), a delay in the delivery of such Notice of Termination shall not
      waive any right of Executive under this Agreement.

                                  ARTICLE IV.

          COMPANY'S OBLIGATIONS UPON CERTAIN TERMINATIONS OF EMPLOYMENT

the Employer terminates Executive's employment other than for Cause or
Disability, or Executive terminates employment for Good Reason, the Company's
sole obligations to Executive under Articles II and IV shall be as set forth in
this Section 4.1.

            Contribution Plans. All amounts previously deferred by, or accrued

            any successor of either of them, or under any non-qualified defined
            contribution or deferred compensation plan of the Company or an
            Affiliate (unless Executive has made an irrevocable election in
            writing, filed with the Company no more than 60 days after the
            Applicable Trigger Date (or such earlier date as counsel to the
            Company may deem to be required to avoid constructive receipt of
            such amounts), and in any event at least 90 days prior to the
            Termination Date to have such amounts paid under the terms of the
            Exelon Corporation Deferred Compensation Plan or the Exelon
            Corporation Deferred Stock Plan, as applicable, or any successor of
            either (including any elections in effect thereunder)) whether
            vested or unvested, together with any accrued earnings thereon, to
            the extent that such amounts and earnings have not been


                                       22
<PAGE>
            previously paid by the Employer and are not provided under the terms
            of either such non-qualified plan;

                  (iv) Pension Enhancements. An amount equal to the positive
            difference, if any, between

                        (1) the lump sum value of Executive's benefit under the
                  SERP, calculated as if Executive had

                              (A) become fully vested in all benefits,

                              (B) attained as of the Termination Date an age
                        that is [THREE/TWO AND ONE-HALF] years greater than
                        Executive's actual age,

                              (C) accrued a number of years of service (for
                        purposes of determining the amount of such benefits,
                        entitlement to - but not commencement of - early
                        retirement benefits, and all other purposes of such
                        defined benefit plans) that is [THREE/TWO AND ONE-HALF]
                        years greater than the number of years of service
                        actually accrued by Executive as of the Termination Date
                        and that includes the number of years of service
                        credited to Executive pursuant to [ANY OTHER AGREEMENT
                        BETWEEN THE COMPANY AND THE EXECUTIVE/SPECIFY
                        AGREEMENT], and

                              (D) received the severance benefits specified in
                        Sections 4.1(a)(ii) and 4.1(a)(vi) as covered
                        compensation in equal monthly installments during the
                        Severance Period,

                        minus

                        (2) the aggregate amounts paid or payable to Executive
                  under the SERP.

                  (v) Unvested Benefits Under Defined Benefit Plan. To the
            extent not paid pursuant to clause (iii) or (iv) of this Section
            4.1(a), an amount equal to the actuarial equivalent present value of
            the unvested portion of Executive's accounts or accrued benefits
            under any tax-qualified (under Section 401(a) of the Code) defined
            benefit retirement plan maintained by the Employer as of the
            Termination Date and forfeited by Executive by reason of the
            Termination of Employment; and

                  (vi) Multiple of Salary and Severance Incentive. An amount
            equal to [THREE (3.0)/TWO AND ONE-HALF (2.5)] times the sum of (x)
            Base Salary plus (y) the Severance Incentive.

            (b) Termination during the Current Post-Merger Period, Post-Change
      Period or Post-Significant Acquisition Period: Stock Options. Each of the
      Executive's stock options, stock appreciation rights or similar incentive
      awards granted under the LTIP ("Stock Options") shall (i) become fully
      vested, and (ii) remain exercisable until (1) the


                                       23
<PAGE>
      option expiration date for any such Stock Options granted prior to January
      1, 2002 or (2) the fifth anniversary of the Termination Date or, if

      or after January 1, 2002.

            (c) Termination during the Current Post-Merger Period, Post-Change
      Period or Post-Significant Acquisition Period: LTIP Vesting. On the
      Termination Date all of the performance shares, performance units or
      similar stock incentive awards granted to the Executive under the Exelon
      Performance Share Program under the LTIP ("Performance Shares") to the
      extent earned by and awarded to the Executive (i.e. as to which the first
      year of the performance cycle has elapsed) as of the Termination Date,
      shall become fully vested at the actual level earned and awarded, and, to
      the extent not yet earned by and awarded to the Executive (i.e. as to
      which the first year of the performance cycle has not elapsed) as of the
      Termination Date, shall become fully vested at the LTIP Target Level.

            (d) Termination During the Current Post-Merger Period, Post-Change
      Period, or Post-Significant Acquisition Period: Other Restricted Stock.
      All forfeiture conditions that as of the Termination Date are applicable
      to any deferred stock unit, restricted stock or restricted share units
      awarded to the Executive by the Company other than under the Exelon
      Performance Share Program under the LTIP ("Restricted Stock") shall lapse
      immediately and all such awards will become fully vested, and within ten
      business days after the Termination Date, the Company shall deliver to
      Executive all of such shares theretofore held by or on behalf of the
      Company.

            (e) Termination During the Current Post-Merger Period, Post-Change
      Period, or Post-Significant Acquisition Period: Continuation of Welfare
      Benefits. During the Severance Period (and continuing through such later
      date as any Welfare Plan may specify), the Company shall continue to
      provide (or shall cause the continued provision) to Executive and
      Executive's family welfare benefits under the Welfare Plans to the same
      extent as if Executive had remained employed during the Severance Period.
      Such provision of welfare benefits shall be subject to the following:

                  (i) In determining benefits applicable under such Welfare
            Plans, the Executive's annual compensation attributable to base
            salary and incentives for any plan year or calendar year, as
            applicable, shall be deemed to be not less than the Executive's Base
            Salary and Annual Incentive.

                  (ii) The cost of such welfare benefits to Executive and family
            under this Section 4.1(e) shall not exceed the cost of such benefits
            to peer executives who are actively employed after the Termination
            Date.

                  (iii) The Executive's rights under this Section 4.1(e) shall
            be in addition to and not in lieu of any post-termination
            continuation coverage or conversion rights the Executive may have
            pursuant to applicable law, including, without limitation,
            continuation coverage required by Section 4980B of the Code.


                                       24
<PAGE>
                  (iv) If the Executive has, as of the last day of the Severance
            Period, attained age 50 and completed at least 10 years of service
            (five years of service for terminations occurring during the Current
            Post-Merger Period), the Executive shall be entitled to the retiree
            benefits provided under any Welfare Plan of the Company; provided,
            however, that for purposes hereof, any years of credited service
            granted to the Executive [IN ANY OTHER PLAN OR AGREEMENT BETWEEN
            EXECUTIVE AND THE COMPANY/SPECIFY AGREEMENT] shall be taken into
            account. For purposes of determining eligibility for (but not the
            time of commencement of) such retiree benefits, the Executive shall
            also be considered (1) to have remained employed until the last day
            of the Severance Period and to have retired on the last day of such
            period, and (2) to have attained at least the age the Executive
            would have attained on the last day of the Severance Period.

      Notwithstanding the foregoing, if the Executive obtains a specific type of
      coverage under welfare plan(s) sponsored by another employer of Executive
      (e.g. medical, prescription, vision, dental, disability, individual life
      insurance benefits, group life insurance benefits, but excluding for the
      purposes of this sentence retiree benefits if Executive is so eligible),
      then the Company shall not be obligated to provide any such specific type
      of coverage.

            (f) Termination during the Current Post-Merger Period, Post-Change
      Period or Post-Significant Acquisition Period: Outplacement. To the extent
      actually incurred by Executive, the Company shall pay or cause to be paid
      on behalf of Executive, as incurred, all reasonable fees and costs charged
      by a nationally recognized outplacement firm selected by the Executive for
      outplacement services provided up to 12 months after the Termination Date.
      No cash shall be paid in lieu of such fees and costs.

            (g) Termination during the Current Post-Merger Period, Post-Change
      Period, or Post-Significant Acquisition Period: Indemnification. The
      Executive shall be indemnified and held harmless by the Company to the
      greatest extent permitted under applicable law as the same now exists or
      may hereafter be amended (but, in the case of any such amendment, only to
      the extent that such amendment permits the Company to provide broader
      indemnification than was permitted prior to such amendment) and the
      Company's by-laws as such exist on the Agreement Date if the Executive
      was, is, or is threatened to be, made a party to any pending, completed or
      threatened action, suit, arbitration, alternate dispute resolution
      mechanism, investigation, administrative hearing or any other proceeding
      whether civil, criminal, administrative or investigative, and whether
      formal or informal, by reason of the fact that the Executive is or was, or
      had agreed to become, a director, officer, employee, agent, or fiduciary
      of the Company or any other entity which the Executive is or was serving
      at the request of the Company ("Proceeding"), against all expenses
      (including all reasonable attorneys' fees) and all claims, damages,
      liabilities and losses incurred or suffered by the Executive or to which
      the Executive may become subject for any reason. A Proceeding shall not
      include any proceeding to the extent it concerns or relates to a matter
      described in Section 6.1(a) (concerning reimbursement of certain costs and
      expenses). Upon receipt from Executive of (i) a written request for an
      advancement of expenses, which Executive reasonably believes will be
      subject to indemnification hereunder and (ii) a written undertaking by
      Executive to repay any such amounts if it shall ultimately be determined
      that Executive is


                                       25
<PAGE>
      not entitled to indemnification under this Agreement or otherwise, the
      Company shall advance such expenses to Executive or pay such expenses for
      Executive, all in advance of the final disposition of any such matter.

            (h) Termination during the Current Post-Merger Period, Post-Change
      Period or Post-Significant Acquisition Period: Directors' and Officers'
      Liability Insurance. For a period of six years after the Termination Date
      (or for any known longer applicable statute of limitations period), the
      Company shall provide Executive with coverage under a directors' and
      officers' liability insurance policy in an amount no less than, and on
      terms no less favorable than, those provided to senior executive officers
      and directors of the Company on the Applicable Trigger Date.

      4.2 Termination During an Imminent Control Change Period. If, during an
Imminent Control Change Period, Executive has a Termination of Employment that
would entitle Executive to benefits under the Exelon Corporation Key Management
Severance Plan or its successor, then the Company shall, prior to the occurrence
of a Change Date, provide Executive any benefits to which Executive may be
entitled under the Exelon Corporation Key Management Severance Plan or its
successor. If, during an Imminent Control Change Period, the Employer terminates
Executive's employment other than for Disability and other than for a reason
that would constitute Cause as defined in Section 3.3(b) or if Executive
terminates employment for a reason that would constitute Good Reason as defined
in Section 3.4(b), then subject to the preceding sentence, unless such
Termination of Employment occurred during the Current Post-Merger Period or the
Post-Significant Acquisition Period, the Company's sole obligations to Executive
under Articles II and IV shall be as set forth in this Section 4.2. The
Company's obligations to Executive under this Section 4.2 shall be reduced by
any amounts or benefits paid or provided pursuant to the Exelon Corporation Key
Management Severance Plan or any successor thereto. If Executive's Termination
of Employment occurred during any portion of an Imminent Control Change Period
that is also the Current Post-Merger Period or a Post-Significant Acquisition
Period, the Company's obligations to Executive, if any, shall be determined
under Section 4.1.

            (a) Termination During an Imminent Control Change Period: Cash
      Severance Payments. If the Imminent Control Change Period culminates in a
      Change Date, the Company shall pay (or cause to be paid) to Executive, a
      lump-sum cash amount, within thirty business days after the later of the
      Termination Date or the Change Date, equal to the sum of all amounts
      described in Section 4.1(a)(i) through (v). The amount described in
      Section 4.1(a)(vi) shall be paid to Executive as described in Section 4.4,
      provided that amounts that would have been paid prior to the Change Date
      shall be paid in a lump sum (without interest) within 30 business days
      after the Change Date.

            (b) Termination During an Imminent Control Change Period: Vested
      Stock Options. Executive's Stock Options, to the extent vested on the
      Termination Date,

                  (i) will not expire (unless such Stock Options would have
            expired had Executive remained an employee of the Company) during
            the Imminent Control Change Period; and


                                       26
<PAGE>
                  (ii) will continue to be exercisable after the Termination
            Date to the extent provided in the applicable grant agreement or
            Plan, and thereafter, such Stock Options shall not be exercisable
            during the Imminent Control Change Period.

      If the Imminent Control Change Period lapses without a Change Date, then
      Executive's Stock Options, to the extent vested on the Termination Date,
      may be exercised, in whole or in part, during the 30-day period following
      the lapse of the Imminent Control Change, or, if larger, the period during
      which Executive's vested Stock Options could otherwise be exercised under
      the terms of the applicable grant agreement or Plan, (but in no case shall
      any Stock Options remain exercisable after the date on which such Stock
      Options would have expired if Executive had remained an employee of the
      Company).

      If the Imminent Control Change Period culminates in a Change Date, then
      effective upon the Change Date, Executive's Stock Options, to the extent
      vested on the Termination Date, may be exercised in whole or in part by
      the Executive at any time until (1) the option expiration date for such
      Stock Options granted prior to January 1, 2002 or (2) the earlier of the
      fifth anniversary of the Change Date or the option expiration date for
      such Stock Options granted on or after January 1, 2002.

            (c) Termination During an Imminent Control Change Period: Unvested
      Stock Options. Executive's Stock Options that are not vested on the
      Termination Date

                  (i) will not expire (unless such Stock Options would have
            expired had Executive remained an employee of the Company) during
            the Imminent Control Change Period; and

                  (ii) will not continue to vest and will not be exercisable
            during the Imminent Control Change Period after the expiration of
            the period for post-termination exercise under the terms of the
            applicable Stock Option Agreement.

      If the Imminent Control Change lapses without a Change Date, such unvested
      Stock Options will thereupon expire.

      If the Imminent Control Change culminates in a Change Date, then
      immediately prior to the Change Date, such unvested Stock Options shall
      become fully vested, and may thereupon be exercised in whole or in part by
      the Executive at any time until (1) the option expiration date for such
      Stock Options granted prior to January 1, 2002 or (2) the earlier of the
      fifth anniversary of the Change Date, or the option expiration date for
      such Stock Options granted on or after January 1, 2002.

            (d) Termination During an Imminent Control Change Period:
      Performance Shares. Executive's Performance Shares granted under the
      Exelon Performance Share Program under the LTIP will not be forfeited
      during the Imminent Control Change Period, and will not continue to vest
      during the Imminent Control Change Period. If the Imminent Control Change
      lapses without a Change Date, such Performance Shares shall be governed
      according to the terms of the Exelon Corporation Key Management Severance
      Plan. If the Imminent Control Change Period culminates in a Change Date:


                                       27
<PAGE>
                  (1) All Performance Shares granted to the Executive under the
            Exelon Performance Share Program under the LTIP, which, as of the
            Termination Date, have been earned by and awarded to the Executive,
            shall become fully vested at the actual earned level on the Change
            Date, and

                  (2) All of the Performance Shares granted to the Executive
            under the Exelon Performance Share Program under the LTIP which, as
            of the Termination Date, have not been earned by and awarded to the
            Executive shall become fully vested on the Change Date at the LTIP
            Target Level.

            (e) Termination During an Imminent Control Change Period: Restricted
      Stock. Executive's unvested Restricted Stock will:

                  (i) not be forfeited during the Imminent Control Change
            Period; and

                  (ii) not continue to vest during the Imminent Control Change
            Period.

      If the Imminent Control Change Period lapses without a Change Date, such
      unvested Restricted Stock shall thereupon be forfeited.

            If the Imminent Control Change Period culminates in a Change Date,
      then immediately prior to the Change Date, Executive's Restricted Stock
      shall become fully vested, and within ten business days after the Change
      Date, the Company shall deliver to Executive all of such shares
      theretofore held by or on behalf of the Company, which will be subject to
      the same terms which other stockholders of the Company receive in the
      transaction.

            (f) Termination During an Imminent Control Change Period:
      Continuation of Welfare Benefits. The Company shall continue to provide to
      Executive and Executive's family welfare benefits (other than any
      severance pay that may be considered a welfare benefit) during the
      Imminent Change Period which are at least as favorable as welfare benefits
      under the most favorable Welfare Plans of the Company applicable with
      respect to peer executives who are actively employed after the Termination
      Date and their families; subject to the following:

                  (i) In determining benefits applicable under such Welfare
            Plans, the Executive's annual compensation attributable to base
            salary and incentives for any plan year or calendar year, as
            applicable, shall be deemed to be not less than the Executive's Base
            Salary and Annual Incentive;

                  (ii) The cost of such welfare benefits to Executive and family
            under this Section 4.2(f) shall not exceed the cost of such benefits
            to peer executives who are actively employed after the Termination
            Date.

                  (iii) Executive's rights under this Section 4.2(f) shall be in
            addition to and not in lieu of any post-termination continuation
            coverage or conversion rights


                                       28
<PAGE>
            the Executive may have pursuant to applicable law, including,
            without limitation, continuation coverage required by Section 4980B
            of the Code.

            If the Imminent Control Change Period lapses without a Change Date,
      welfare benefit plan coverage under this Section 4.2(f) shall thereupon
      cease, subject to Executive's rights, if any, to continued coverage under
      a Welfare Plan, the Exelon Corporation Key Management Severance Plan, or
      applicable law. If the Imminent Control Change Period culminates in a
      Change Date, then for the remainder of the Severance Period (and
      continuing through such later date as any Welfare Plan may specify), the
      Company shall continue to provide Executive and Executive's family welfare
      benefits as described in, and subject to the limitations of Section
      4.1(e).

      Notwithstanding the foregoing, if the Executive obtains a specific type of
coverage under welfare plan(s) sponsored by another employer of Executive (e.g.
medical, prescription, vision, dental, disability, individual life insurance
benefits, group life insurance benefits, but excluding for the purposes of this
sentence retiree benefits if Executive is so eligible), then the Company shall
not be obligated to provide such any specific type of coverage.

            (g) Termination During an Imminent Control Change Period:
      Outplacement. To the extent actually incurred by Executive, the Company
      shall pay or cause to be paid on behalf of Executive, as incurred, all
      reasonable fees and costs charged by a nationally recognized outplacement
      firm selected by the Executive for outplacement services provided up to 12
      months after the Termination Date. No cash shall be paid in lieu of such
      fees and costs.

            (h) Termination During an Imminent Control Change Period:
      Indemnification. The Executive shall be indemnified and held harmless by
      the Company to the same extent as provided in Section 4.1(g), but only
      during the Imminent Control Change Period (or greater period provided
      under the Company's by-laws) if the Imminent Control Change Period lapses
      without a Change Date.

            (i) Termination During an Imminent Control Change Period: Directors'
      and Officers' Liability Insurance. The Company shall provide the same
      level of directors' and officers' liability insurance for Executive as
      provided in Section 4.1(h), but only during the Imminent Control Change
      Period (or greater period provided under the Company's by-laws) if the
      Imminent Control Change Period lapses without a Change Date.

      4.3 Termination During a Post-Disaggregation Period. If, during a
Post-Disaggregation Period the Disaggregated Entity terminates Executive's
employment other than for Cause or Disability, or if Executive terminates
employment for Good Reason, the Company's sole obligations to Executive under
Articles II and IV shall be as set forth in this Section 4.3, subject to Section
3.3(a)(iii), but only to the extent not provided by the Disaggregated Entity.

            (a) Termination During a Post-Disaggregation Period: Cash Severance
      Payments. The Company shall pay Executive the amounts described in Section
      4.1(a), as provided in Section 4.4.


                                       29
<PAGE>
            (b) Termination During a Post-Disaggregation Period: Stock Options.
      All of Executive's Stock Options granted prior to the Disaggregation that
      have not expired, whether or not converted to options or stock of the
      Disaggregated Entity or Merger Survivor, shall be fully vested, and may be
      exercised in whole or in part by the Executive at any time until (1) the
      remaining option expiration date for such Stock Options granted prior to
      January 1, 2002 and (2) the earlier of the fifth anniversary of the
      Termination Date or the option expiration date for such Stock Options
      granted on or after January 1, 2002.

            (c) Termination During a Post-Disaggregation Period: Performance
      Shares. Executive's Performance Shares granted prior to the
      Disaggregation, whether or not earned by and awarded to the Executive as
      of the Disaggregation, and whether or not converted to performance shares
      of the Disaggregated Entity or the Merger Survivor, shall become fully
      vested (at the earned level for Performance Shares earned and awarded, and
      at the target level for any converted performance shares not yet earned
      and awarded) on the Termination Date.

            (d) Termination During a Post-Disaggregation Period: Restricted
      Stock. Executive's unvested Restricted Stock, whether or not converted to
      restricted stock of the Disaggregated Entity or Merger Survivor, shall
      become fully vested on the Termination Date.

            (e) Termination During a Post-Disaggregation Period: Continuation of
      Welfare Benefits. Until the end of the Severance Period, the Company shall
      continue to provide to Executive and Executive's family welfare benefits
      with the same rights in relation to continuation coverage, status in
      relation to other employer benefits, scope and cost as described in
      Section 4.1(e); provided that, to the extent Executive is eligible for
      post-termination continuation coverage under the plans of the
      Disaggregated Entity, whether pursuant to Section 4980B of the Code or
      otherwise, the continued coverage required hereunder shall be provided
      under the plans of the Disaggregated Entity (and the Company shall
      reimburse the cost to Executive of such coverage).

            (f) Termination During a Post-Disaggregation Period: Outplacement.
      To the extent actually incurred by Executive, the Company shall pay or
      cause to be paid on behalf of Executive, as incurred, all reasonable fees
      and costs charged by a nationally recognized outplacement firm selected by
      the Executive for outplacement services provided up to 12 months after the
      Termination Date. No cash shall be paid in lieu of such fees and costs.

            (g) Termination During a Post-Disaggregation Period:
      Indemnification. The Executive shall be indemnified and held harmless by
      the Company to the same extent as provided in Section 4.1(g).

            (h) Termination During a Post-Disaggregation Period: Directors' and
      Officers' Liability Insurance. The Company shall provide Executive with
      directors' and officers' liability insurance to the same extent as
      provided in Section 4.1(h).

      4.4 Timing of Severance Payments. Unless otherwise specified herein, the
amounts described in Sections 4.1(a)(i), (ii), (iii), (iv) and (v) shall be paid
within 30 business days of the Termination Date. The severance payments

            (a) Beginning no later than the second paydate which occurs after
      the Termination Date, the Company shall make periodic payments to the
      Executive according to the Company's normal payroll practices at a monthly
      rate equal to 1/12 of the sum of (i) the Executive's Base Salary in effect
      as of the Termination Date plus (ii) the Severance Incentive; and

            (b) Within 30 business days of the second anniversary of the
      Termination Date, the Company shall pay Executive a cash lump sum equal to
      the difference between the total Severance Payment less the total amount
      paid pursuant to normal payroll practices under Section 4.4(a).

      4.5 Waiver and Release. Notwithstanding anything herein to the contrary,
the Company shall have no obligation to Executive under Article IV or Article V
unless and until Executive executes a release and waiver of Company and its
Affiliates, in substantially the same form as attached hereto as Exhibit A, or
as otherwise mutually acceptable.

      4.6 Breach of Covenants. If a court determines that Executive has breached
any non-competition, non-solicitation, confidential information or intellectual
property covenant entered into between Executive and Company, the Company shall
not be obligated to pay or provide any severance or benefits under Articles IV
or V, all unexercised Stock Options shall terminate as of the date of the
breach, and all Restricted Stock shall be forfeited as of the date of the
breach.

      4.7 Termination by the Company for Cause. If the Company (or Affiliate or,
if applicable, the Disaggregated Entity) terminates Executive's employment for
Cause during the Current Post-Merger Period, the Post-Change Period, the
Imminent Control Change Period, the Post-Significant Acquisition Period, or the
Post-Disaggregation Period, the Company's sole obligation to Executive under
Articles II, IV, and V shall be to pay Executive, pursuant to the Company's
then-effective Plans, a lump-sum cash amount equal to all Accrued Obligations
determined as of the Termination Date. The remaining applicable provisions of
this Agreement (including the restrictive covenants in Article IX) shall
continue to apply.

      4.8 Termination by Executive Other Than for Good Reason. If Executive
elects to retire or otherwise terminate employment during the Current
Post-Merger Period, the Post-Change Period, the Imminent Control Change Period,
the Post-Significant Acquisition Period, or the Post-Disaggregation Period,
other than for Good Reason, Disability or death, the Company's sole obligation
to Executive under Articles II, IV, and V shall be to pay Executive, pursuant to
the Company's then-effective Plans, a lump-sum cash amount equal to all Accrued
Obligations determined as of the Termination Date. The remaining provisions of
this Agreement (including the restrictive covenants in Article IX) shall
continue to apply.

      4.9 Termination by the Company for Disability. If the Company (or
Disaggregated Entity, if applicable) terminates Executive's employment by reason
of Executive's Disability


                                       31
<PAGE>
during the Current Post-Merger Period, Post-Change Period, Imminent Control
Change Period that culminates in a Change Date, Post-Significant Acquisition
Period or Post-Disaggregation Period, the Company's sole obligation to Executive
under Articles II, IV, and V shall be as follows, and such obligations shall be

      executives of the Company in effect immediately before the Termination
      Date.

      The remaining provisions of this Agreement (including the restrictive
covenants in Article IX) shall continue to apply.

      4.10 Upon Death. If Executive's employment is terminated by reason of
Executive's death during the Current Post-Merger Period, Post-Change Period,
Imminent Control Change Period that culminates in a Change Date,
Post-Significant Acquisition Period or Post-Disaggregation Period, the Company's
sole obligations to Executive and Executive's Beneficiary under Articles II, IV,
and V shall be as follows, and such obligations shall be reduced by amounts paid
or provided by the Disaggregated Entity:

            (a) to pay Executive's Beneficiary, pursuant to the Company's
      then-effective Plans, a lump-sum cash amount equal to all Accrued
      Obligations; and

            (b) to provide Executive's Beneficiary survivor and other benefits
      that are not less than the most favorable of such benefits then available
      under Plans of the Company to surviving families of peer executives of the
      Company in effect immediately before the Executive's death, [TAKING INTO
      ACCOUNT THE YEARS, IF ANY, OF CREDITED SERVICE GRANTED TO THE EXECUTIVE
      UNDER] [CUSTOMIZE WITH SPECIFIC PROVISIONS FOR RETIREE/SURVIVOR COVERAGE.]

      4.11 Sole and Exclusive Obligations. The obligations of the Company under
this Agreement with respect to any Termination of Employment of the Executive
during the Current Post-Merger Period, Post-Change Period, Imminent Control
Change Period, Post-Significant Acquisition Period, or Post-Disaggregation
Period shall, except as provided in Section 4.2, supersede any severance
obligations of the Company in any other plan of the Company or agreement between
Executive and the Company, including, without limitations, the Exelon
Corporation Key Management Severance Plan, any Change in Control Agreement
entered into by and among Executive, Unicom Corporation, Commonwealth Edison
Company, or PECO Energy Company or any other plan or agreement (including an
offer of employment or employment contract) of the Company or any Affiliates
which provides for severance benefits. In the event of any inconsistency,
ambiguity or conflict between the terms of such other plan of the Company or
agreement between Executive and the Company and this Agreement with respect to
any severance obligations of the Company (other than obligations with respect to


                                       32
<PAGE>
credited service under the SERP in any agreement other than a prior Change in
Control Agreement entered into by and among Executive, Unicom Corporation,
Commonwealth Edison Company or PECO Energy Company), this Agreement shall
govern.

                                   ARTICLE V.

                   CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

      5.1 Gross-Up Payment. If at any time or from time to time, it shall be
determined by the Company's independent auditors that any payment or other
benefit to Executive pursuant to Article II or Article IV of this Agreement or
otherwise ("Potential Parachute Payment") is or will become subject to the
excise tax imposed by Section 4999 of the Code or any similar tax payable under
any United States federal, state, local, foreign or other law ("Excise Taxes"),
then the Company shall, subject to Section 5.2, pay or cause to be paid a tax
gross-up payment ("Gross-Up Payment") with respect to all such Excise Taxes and
other Taxes on the Gross-Up Payment. The Gross-Up Payment shall be an amount
equal to the product of

            (a) The amount of the Excise Taxes (calculated at the effective
      marginal rates of all federal, state, local, foreign or other law),

      multiplied by

            (b) A fraction (the "Gross-Up Multiple"), the numerator or which is
      one (1.0), and the denominator of which is one (1.0) minus the lesser of
      (i) the sum, expressed as a decimal fraction, of the effective marginal
      rates of any Taxes and any Excise Taxes applicable to the Gross-Up Payment
      or (ii) .80, it being intended that the Gross-Up Multiple shall in no
      event exceed five (5.0). If different rates of tax are applicable to
      various portions of a Gross-Up Payment, the weighted average of such rates
      shall be used. For purposes of this Section, Executive shall be deemed to
      be subject to the highest effective marginal rate of Taxes.

The Gross-Up Payment is intended to compensate Executive for all such Excise
Taxes and any other Taxes payable by Executive with respect to the Gross-Up
Payment. The Company shall pay or cause to be paid the Gross-Up Payment to
Executive within thirty (30) days of the calculation of such amount, but in no
event after the Executive makes payment to the IRS of such Excise Taxes.

      5.2 Limitation on Gross-Up Payments.

            (a) To the extent possible, any payments or other benefits to
      Executive pursuant to Article II and Article IV of this Agreement shall be
      allocated as consideration for Executive's entry into the covenants of
      Article IX.

            (b) Notwithstanding any other provision of this Article V, if the
      aggregate amount of the Potential Parachute Payments that, but for this
      Section 5.2, would be payable to Executive, does not exceed 110% of Floor
      Amount (as defined below), then no Gross-Up Payment shall be made to
      Executive and the aggregate amount of Potential Parachute Payments payable
      to Executive shall be reduced (but not below the Floor


                                       33
<PAGE>
      Amount) to the largest amount which would both (i) not cause any Excise
      Tax to be payable by Executive and (ii) not cause any Potential Parachute
      Payments to become nondeductible by the Company by reason of Section 280G
      of the Code (or any successor provision). For purposes of the preceding
      sentence, "Floor Amount" means the greatest pre-tax amount of Potential
      Parachute Payments that could be paid to Executive without causing
      Executive to become liable for any Excise Taxes in connection therewith.

      5.3 Additional Gross-up Amounts. If, for any reason (whether pursuant to
subsequently enacted provisions of the Code, final regulations or published
rulings of the IRS, or a final judgment of a court of competent jurisdiction)
the Company's independent auditors later determine that the amount of Excise
Taxes payable by Executive is greater than the amount initially determined
pursuant to Section 5.1, then the Company shall, subject to Sections 5.2 and
5.4, pay Executive, within thirty (30) days of such determination, or pay to the
IRS as required by applicable law, an amount (which shall also be deemed a
Gross-Up Payment) equal to the product of:

            (a) the sum of (i) such additional Excise Taxes and (ii) any
      interest, penalties, expenses or other costs incurred by Executive as a
      result of having taken a position in accordance with a determination made
      pursuant to Section 5.1 or 5.4,

multiplied by

            (b) the Gross-Up Multiple.

      5.4 Amount Increased or Contested.

            (a) Executive shall notify the Company in writing (an "Executive's
      Notice") of any claim by the IRS or other taxing authority (an "IRS
      Claim") that, if successful, would require the payment by Executive of
      Excise Taxes in respect of Potential Parachute Payments in an amount in
      excess of the amount of such Excise Taxes determined in accordance with
      Section 5.1. Executive's Notice shall include the nature and amount of
      such IRS Claim, the date on which such IRS Claim is due to be paid (the
      "IRS Claim Deadline"), and a copy of all notices and other documents or
      correspondence received by Executive in respect of such IRS Claim.
      Executive shall give the Executive's Notice as soon as practicable, but no
      later than the earlier of (i) 10 days after Executive first obtains actual
      knowledge of such IRS Claim or (ii) five days before the IRS Claim
      Deadline; provided, however, that any failure to give such Executive's
      Notice shall affect the Company's obligations under this Article only to
      the extent that the Company is actually prejudiced by such failure. If at
      least one business day before the IRS Claim Deadline the Company shall:

                  (i) deliver to Executive a written certificate from the
            Company's independent auditors ("Company Certificate") to the effect
            that, notwithstanding the IRS Claim, the amount of Excise Taxes,
            interest or penalties payable by Executive is either zero or an
            amount less than the amount specified in the IRS Claim,


                                       34
<PAGE>
                  (ii) pay to Executive, or to the IRS as required by applicable
            law, an amount (which shall also be deemed a Gross-Up Payment) equal
            to difference between the product of (A) amount of Excise Taxes,
            interest and penalties specified in the Company Certificate, if any,
            multiplied by (B) the Gross-Up Multiple, less the portion of such
            product, if any, previously paid to Executive by the Company, and

                  (iii) direct Executive pursuant to Section 5.4(d) to contest
            the balance of the IRS Claim,

      then Executive shall pay only the amount, if any, of Excise Taxes,
      interest and penalties specified in the Company Certificate. In no event
      shall Executive pay an IRS Claim earlier than 30 business days after
      having given an Executive's Notice to the Company (or, if sooner, the IRS
      Claim Deadline).

            (b) At any time after the payment by Executive of any amount of
      Excise Taxes, other Taxes or related interest or penalties in respect of
      Potential Parachute Payments (including any such amount equal to or less
      than the amount of such Excise Taxes specified in any Company Certificate,
      or IRS Claim), the Company may in its discretion require Executive to
      pursue a claim for a refund (a "Refund Claim") of all or any portion of
      such Excise Taxes, other Taxes, interest or penalties as may be specified
      by the Company in a written notice to Executive.

            (c) If the Company notifies Executive in writing that the Company
      desires Executive to contest an IRS Claim or to pursue a Refund Claim,
      Executive shall:

                  (i) give the Company all information that it reasonably
            requests in writing from time to time relating to such IRS Claim or
            Refund Claim, as applicable,

                  (ii) take such action in connection with such IRS Claim or
            Refund Claim (as applicable) as the Company reasonably requests in
            writing from time to time, including accepting legal representation
            with respect thereto by an attorney selected by the Company, subject
            to the approval of Executive (which approval shall not be
            unreasonably withheld or delayed),

                  (iii) cooperate with the Company in good faith to contest such
            IRS Claim or pursue such Refund Claim, as applicable,

                  (iv) permit the Company to participate in any proceedings
            relating to such IRS Claim or Refund Claim, as applicable, and

                  (v) contest such IRS Claim or prosecute Refund Claim (as
            applicable) to a determination before any administrative tribunal,
            in a court of initial jurisdiction and in one or more appellate
            courts, as the Company may from time to time determine in its
            discretion.


                                       35
<PAGE>
      The Company shall control all proceedings in connection with such IRS
      Claim or Refund Claim (as applicable) and in its discretion may cause
      Executive to pursue or forego any and all administrative appeals,
      proceedings, hearings and conferences with the Internal Revenue Service or
      other taxing authority in respect of such IRS Claim or Refund Claim (as
      applicable); provided that (i) any extension of the statute of limitations
      relating to payment of taxes for the taxable year of Executive relating to
      the IRS Claim is limited solely to such IRS Claim, (ii) the Company's
      control of the IRS Claim or Refund Claim (as applicable) shall be limited
      to issues with respect to which a Gross-Up Payment would be payable, and
      (iii) Executive shall be entitled to settle or contest, as the case may
      be, any other issue raised by the Internal Revenue Service or other taxing
      authority.

            (d) The Company may at any time in its discretion direct Executive
      to (i) contest the IRS Claim in any lawful manner or (ii) pay the amount
      specified in an IRS Claim and pursue a Refund Claim; provided, however,
      that if the Company directs Executive to pay an IRS Claim and pursue a
      Refund Claim, the Company shall advance the amount of such payment to
      Executive on an interest-free basis and shall indemnify Executive, on an
      after-tax basis, for any Excise Tax or income tax, including related
      interest or penalties, imposed with respect to such advance.

            (e) The Company shall pay directly all legal, accounting and other
      costs and expenses (including additional interest and penalties) incurred
      by the Company or Executive in connection with any IRS Claim or Refund
      Claim, as applicable, and shall indemnify Executive, on an after-tax
      basis, for any Excise Tax or income tax, including related interest and
      penalties, imposed as a result of such payment of costs and expenses.

      5.5 Refunds. If, after the receipt by Executive or the IRS of any payment
or advance of Excise Taxes or other Taxes by the Company pursuant to this
Article, Executive receives any refund with respect to such Excise Taxes,
Executive shall (subject to the Company's complying with any applicable
requirements of Section 5.4) promptly pay the Company the amount of such refund
(together with any interest paid or credited thereon after taxes applicable
thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 5.4 or receipt by the IRS of an amount paid by the
Company on behalf of the Executive pursuant to Section 5.4, a determination is
made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to
contest such determination within 30 days after the Company receives written
notice of such determination, then such advance shall be forgiven and shall not
be required to be repaid and the amount of such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid. Any contest
of a denial of refund shall be controlled by Section 5.4(d).

                                  ARTICLE VI.

                    EXPENSES, INTEREST AND DISPUTE RESOLUTION

      6.1 Enforcement and Late Payments.

            (a) If, after the Agreement Date, Executive incurs reasonable legal
      fees or other expenses (including arbitration costs and expenses under
      Section 6.3) in an effort to


                                       36
<PAGE>
      secure, preserve, or obtain benefits under this Agreement, the Company
      shall, regardless of the outcome of such effort, reimburse Executive (in
      accordance with Section 6.1(b)) for such fees and expenses.

            (b) Reimbursement of legal fees and expenses and gross-up payments
      shall be made on a current basis, promptly after Executive's written
      submission of a request for reimbursement together with evidence that such
      fees and expenses were incurred.

            (c) If Executive does not prevail (after exhaustion of all available
      judicial remedies) in respect of a claim by Executive or by the Company
      hereunder, and the Company establishes before a court of competent
      jurisdiction by clear and convincing evidence that Executive had no
      reasonable basis for Executive's claim hereunder, or for Executive's
      response to the Company's claim hereunder, or that Executive acted in bad
      faith, no further reimbursement for legal fees and expenses shall be due
      to Executive in respect of such claim and Executive shall refund any
      amounts previously reimbursed hereunder with respect to such claim.

      6.2 Interest. If the Company does not pay any cash amount due to Executive
under this Agreement within three business days after such amount first became
due and owing, interest shall accrue on such amount from the date it became due
and owing until the date of payment at an annual rate equal to 200 basis points
above the base commercial lending rate published in The Wall Street Journal in
effect from time to time during the period of such nonpayment; provided that the
Executive shall not be entitled to interest on any Gross Up Payment.

      6.3 Arbitration. Any dispute, controversy or claim between the parties
hereto arising out of or in connection with or relating to this Agreement (other
than disputes related to Article V or to an alleged breach of the covenant
contained in Article IX) or any breach or alleged breach thereof, or any benefit
or alleged benefit hereunder, shall be settled by arbitration in Chicago,
Illinois, before an impartial arbitrator pursuant to the rules and regulations
of the American Arbitration Association ("AAA") pertaining to the arbitration of
labor disputes. Either party may invoke the right to arbitration. The arbitrator
shall be selected by means of the parties striking alternatively from a panel of
seven arbitrators supplied by the Chicago office of AAA. The arbitrator shall
have the authority to interpret and apply the provisions of this Agreement,
consistent with Section 11.11 below. The decision of the arbitrator shall be
final and binding upon the parties and a judgment thereon may be entered in the
highest court of a forum, state or federal, having jurisdiction. The expenses of
the arbitration shall be borne according to Section 6.1. No arbitration shall be
commenced after the date when institution of legal or equitable proceedings
based upon such subject matter would be barred by the applicable statutes of
limitations. Notwithstanding anything to the contrary contained in this Section
6.3 or elsewhere in this Agreement, either party may bring an action in the
District Court of Cook County, or the United States District Court for the
Northern District of Illinois, if jurisdiction there lies, in order to maintain
the status quo ante of the parties. The "status quo ante" is defined as the last
peaceable, uncontested status between the parties. However, neither the party
bringing the action nor the party defending the action thereby waives its right
to arbitration of any dispute, controversy or claim arising out of or in
connection or relating to this Agreement. Notwithstanding anything to the
contrary contained in this Section 6.3 or elsewhere in this


                                       37
<PAGE>
Agreement, either party may seek relief in the form of specific performance,
injunctive or other equitable relief in order to enforce the decision of the
arbitrator. The parties agree that in any arbitration commenced pursuant to this
Agreement, the parties shall be entitled to such discovery (including
depositions, requests for the production of documents and interrogatories) as
would be available in a federal district court pursuant to Rules 26 through 37
of the Federal Rules of Civil Procedure. In the event that either party fails to
comply with its discovery obligations hereunder, the arbitrator shall have full
power and authority to compel disclosure or impose sanctions to the full extent
of Rule 37 of the Federal Rules of Civil Procedure.

                                  ARTICLE VII.

                    NO ADVERSE EFFECT ON POOLING OF INTERESTS

      Any benefits provided to the Executive under this Agreement may be reduced
or eliminated to the extent necessary, in the reasonable judgment of the Board,
to enable the Company to account for a merger, consolidation or similar
transaction as a pooling of interests; provided that (i) the Board shall have
exercised such judgment and given the Executive written notice thereof prior to
the Change Date and (ii) the determination of the Board shall be supported by a
written certificate of the Company's independent auditors, a copy of which shall
be provided to the Executive before the Change Date.

                                 ARTICLE VIII.

                            NO SET-OFF OR MITIGATION

      8.1 No Set-off by Company. Executive's right to receive when due the
payments and other benefits provided for under this Agreement is absolute,
unconditional and subject to no setoff, counterclaim or legal or equitable
defense. Time is of the essence in the performance by the Company of its
obligations under this Agreement. Any claim which the Company may have against
Executive, whether for a breach of this Agreement or otherwise, shall be brought
in a separate action or proceeding and not as part of any action or proceeding
brought by Executive to enforce any rights against the Company under this
Agreement.

      8.2 No Mitigation. Executive shall not have any duty to mitigate the
amounts payable by the Company under this Agreement by seeking new employment or
self-employment following termination. Except as specifically otherwise provided
in this Agreement, all amounts payable pursuant to this Agreement shall be paid
without reduction regardless of any amounts of salary, compensation or other
amounts which may be paid or payable to Executive as the result of Executive's
employment by another employer or self-employment.

                                  ARTICLE IX.

                              RESTRICTIVE COVENANTS

      9.1 Confidential Information. The Executive acknowledges that in the
course of performing services for the Companies and Affiliates, he may create
(alone or with others), learn of, have access to and receive Confidential
Information. Confidential Information shall not


                                       38
<PAGE>
include: (i) information that is or becomes generally known through no fault of
Executive; (ii) information received from a third party outside of the Company
that was disclosed without a breach of any confidentiality obligation; or (iii)
information approved for release by written authorization of the Company. The
Executive recognizes that all such Confidential Information is the sole and
exclusive property of the Company and its Affiliates or of third parties which
the Company or Affiliate is obligated to keep confidential, that it is the
Company's policy to keep all such Confidential Information confidential, and
that disclosure of Confidential Information would cause damage to the Company
and its Affiliates. The Executive agrees that, except as required by the duties
of Executive's employment with the Company or any of its Affiliates and except
in connection with enforcing the Executive's rights under this Agreement or if
compelled by a court or governmental agency, in each case provided that prior
written notice is given to Company, Executive will not, without the written
consent of Company, willfully disseminate or otherwise disclose, directly or
indirectly, any Confidential Information obtained during his employment with the
Company or its Affiliates, and will take all necessary precautions to prevent
disclosure, to any unauthorized individual or entity inside or outside the
Company, and will not use the Confidential Information or permit its use for the
benefit of Executive or any other person or entity other than the Company or its
Affiliates. These obligations shall continue during and after the termination of
Executive's employment (whether or not after a Change in Control, Imminent
Control Change, Significant Acquisition or Disaggregation).

      9.2 Non-Competition. During the period beginning on the Agreement Date and
ending on the second anniversary of the Termination Date, whether or not after a
Change in Control, Imminent Control Change, Significant Acquisition or
Disaggregation, Executive hereby agrees that without the written consent of the
Company Executive shall not at any time, directly or indirectly, in any
capacity:

            (a) engage or participate in, become employed by, serve as a
      director of, or render advisory or consulting or other services in
      connection with, any Competitive Business; provided, however, that after
      the Termination Date this Section 9.2 shall not preclude Executive from
      being an employee of, or consultant to, any business unit of a Competitive
      Business if (i) such business unit does not qualify as a Competitive
      Business in its own right and (ii) Executive does not have any direct or
      indirect involvement in, or responsibility for, any operations of such
      Competitive Business that cause it to qualify as a Competitive Business.

            (b) make or retain any financial investment, whether in the form of
      equity or debt, or own any interest, in any Competitive Business. Nothing
      in this subsection shall, however, restrict Executive from making an
      investment in any Competitive Business if such investment does not (i)
      represent more than 1% of the aggregate market value of the outstanding
      capital stock or debt (as applicable) of such Competitive Business, (ii)
      give Executive any right or ability, directly or indirectly, to control or
      influence the policy decisions or management of such Competitive Business,
      and (iii) create a conflict of interest between Executive's duties under
      this Agreement and his interest in such investment.

      9.3 Non-Solicitation. During the period beginning on the Agreement Date
and ending on the second anniversary of any Termination Date, whether or not
after a Change in


                                       39
<PAGE>
Control, Imminent Control Change, Significant Acquisition or Disaggregation,
Executive shall not, directly or indirectly:

            (a) other than in connection with the good-faith performance of his
      duties as an officer of the Company, cause or attempt to cause any
      employee or agent of the Company to terminate his or her relationship with
      the Company;

            (b) employ, engage as a consultant or adviser, or solicit the
      employment or engagement as a consultant or adviser, of any employee or
      agent of the Company (other than by the Company or its Affiliates), or
      cause or attempt to cause any Person to do any of the foregoing;

            (c) establish (or take preliminary steps to establish) a business
      with, or cause or attempt to cause others to establish (or take
      preliminary steps to establish) a business with, any employee or agent of
      the Company, if such business is or will be a Competitive Business; or

            (d) interfere with the relationship of the Company with, or endeavor
      to entice away from the Company, any Person who or which at any time
      during the period commencing one year prior to the Termination Date was or
      is, to the Executive's knowledge, a material customer or material supplier
      of, or maintained a material business relationship with, the Company.

      9.4 Intellectual Property. During the period of Executive's employment
with the Company and any Affiliate, and thereafter upon the Company's request,
whether or not after a Change in Control, Imminent Control Change, Significant
Acquisition or Disaggregation, Executive shall disclose immediately to the
Company all ideas, inventions and business plans that he makes, conceives,
discovers or develops alone or with others during the course of his employment
with the Company or during the one year period following Executive's Termination
Date, including any inventions, modifications, discoveries, developments,
improvements, computer programs, processes, products or procedures (whether or
not protectable upon application by copyright, patent, trademark, trade secret
or other proprietary rights) ("Work Product") that: (i) relate to the business
of the Company or any customer or supplier to the Company or any of the products
or services being developed, manufactured, sold or otherwise provided by the
Company or that may be used in relation therewith; or (ii) result from tasks
assigned to Executive by the Company; or (iii) result from the use of the
premises or personal property (whether tangible or intangible) owned, leased or
contracted for by the Company. Executive agrees that any Work Product shall be
the property of the Company and, if subject to copyright, shall be considered a
"work made for hire" within the meaning of the Copyright Act of 1976, as amended
(the "Act"). If and to the extent that any such Work Product is not a "work made
for hire" within the meaning of the Act, Executive hereby assigns to the Company
all right, title and interest in and to the Work Product, and all copies
thereof, and the copyright, patent, trademark, trade secret and all proprietary
rights in the Work Product, without further consideration, free from any claim,
lien for balance due or rights of retention thereto on the part of Executive.


                                       40
<PAGE>
            (a) The Company hereby notifies Executive that the preceding
      paragraph does not apply to any inventions for which no equipment,
      supplies, facility, or trade secret information of the Company was used
      and which was developed entirely on the Executive's own time, unless: (i)
      the invention relates (a) to the Company's business, or (b) to the
      Company's actual or demonstrably anticipated research or development, or
      (ii) the invention results from any work performed by the Executive for
      the Company.

            (b) Executive agrees that upon disclosure of Work Product to the
      Company, Executive will, during his employment and at any time thereafter,
      at the request and cost of the Company, execute all such documents and
      perform all such acts as the Company or its duly authorized agents may
      reasonably require: (i) to apply for, obtain and vest in the name of the
      Company alone (unless the Company otherwise directs) letters patent,
      copyrights or other analogous protection in any country throughout the
      world, and when so obtained or vested to renew and restore the same; and
      (ii) to prosecute or defend any opposition proceedings in respect of such
      applications and any opposition proceedings or petitions or applications
      for revocation of such letters patent, copyright or other analogous
      protection, or otherwise in respect of the Work Product.

            (c) In the event that the Company is unable, after reasonable
      effort, to secure Executive's execution as provided in subsection (b)
      above, whether because of Executive's physical or mental incapacity or for
      any other reason whatsoever, Executive hereby irrevocably designates and
      appoints the Company and its duly authorized officers and agents as his
      agent and attorney-in-fact, to act for and on his behalf to execute and
      file any such application or applications and to do all other lawfully
      permitted acts to further the prosecution, issuance and protection of
      letters patent, copyright and other intellectual property protection with
      the same legal force and effect as if personally executed by Executive.

      9.5 Reasonableness of Restrictive Covenants.

            (a) Executive acknowledges that the covenants contained in Sections
      9.1, 9.2, 9.3 and 9.4 are reasonable in the scope of the activities
      restricted, the geographic area covered by the restrictions, and the
      duration of the restrictions, and that such covenants are reasonably
      necessary to protect the Company's legitimate interests in its
      Confidential Information and in its relationships with its employees,
      customers and suppliers. Executive further acknowledges such covenants are
      essential elements of this Agreement and that, but for such covenants, the
      Company would not have entered into this Agreement.

            (b) The Company and Executive have each consulted with their
      respective legal counsel and have been advised concerning the
      reasonableness and propriety of such covenants. Executive acknowledges
      that his observance of the covenants contained in Sections 9.1, 9.2, 9.3
      and 9.4 will not deprive Executive of the ability to earn a livelihood or
      to support his dependents.

      9.6 Right to Injunction; Survival of Undertakings.


                                       41
<PAGE>
            (a) In recognition of the confidential nature of the Confidential
      Information, and in recognition of the necessity of the limited
      restrictions imposed by Sections 9.1, 9.2, 9.3 and 9.4 the parties agree
      that it would be impossible to measure solely in money the damages which
      the Company would suffer if Executive were to breach any of his
      obligations under such Sections. Executive acknowledges that any breach of
      any provision of such Sections would irreparably injure the Company.
      Accordingly, Executive agrees that if he breaches any of the provisions of
      such Sections, the Company shall be entitled, in addition to any other
      remedies to which the Company may be entitled under this Agreement or
      otherwise, to an injunction to be issued by a court of competent
      jurisdiction, to restrain any breach, or threatened breach, of such
      provisions, and Executive hereby waives any right to assert any claim or
      defense that the Company has an adequate remedy at law for any such
      breach.

            (b) If a court determines that any of the covenants included in this
      Article IX is unenforceable in whole or in part because of such covenant's
      duration or geographical or other scope, such court shall have the power
      to modify the duration or scope of such provision, as the case may be, so
      as to cause such covenant as so modified to be enforceable.

            (c) All of the provisions of this Article IX shall survive any
      Termination of Employment without regard to (i) the reasons for such
      termination or (ii) the expiration of the Agreement Term.

            (d) The Company shall have no further obligation to pay or provide
      severance or benefits under Article II, Article IV, or Article V if a
      court determines that the Executive has breached any covenant in this
      Article IX.

                                   ARTICLE X.

                            NON-EXCLUSIVITY OF RIGHTS

      10.1 Other Rights. Except as expressly provided in Section 4.11 or
elsewhere in this Agreement, this Agreement shall not prevent or limit
Executive's continuing or future participation in any benefit, bonus, incentive
or other Plans provided by the Company and for which Executive may qualify, nor
shall this Agreement limit or otherwise affect such rights as Executive may have
under any other agreements with the Company. Amounts which are vested benefits
or which Executive is otherwise entitled to receive under any Plan and any other
payment or benefit required by law at or after the Termination Date shall be
payable in accordance with such Plan or applicable law except as expressly
modified by this Agreement.

      10.2 No Right to Continued Employment. Nothing in this Agreement shall
guarantee the right of Executive to continue in employment, and the Company
retains the right to terminate the Executive's employment at any time for any
reason or for no reason.

                                  ARTICLE XI.

                                  MISCELLANEOUS


                                       42
<PAGE>
      11.1 No Assignability. This Agreement is personal to Executive and without
the prior written consent of the Company shall not be assignable by Executive
otherwise than by will or the laws of descent and distribution. This Agreement
shall inure to the benefit of and be enforceable by Executive's legal
representatives.

      11.2 Successors. This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns. The Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to assume expressly and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Any successor to the business
or assets of the Company which assumes or agrees to perform this Agreement by
operation of law, contract, or otherwise shall be jointly and severally liable
with the Company under this Agreement as if such successor were the Company.

      11.3 Affiliates. To the extent that immediately prior to the Applicable
Trigger Date, the Executive has been on the payroll of, and participated in the
incentive or employee benefit plans of, an Affiliate of the Company, the
references to the Company contained in Sections 2.9(a)(i) through (vi) and the
other Sections of this Agreement referring to benefits to which the Executive
may be entitled shall be read to refer to such Affiliate.

      11.4 Payments to Beneficiary. If Executive dies before receiving amounts
to which Executive is entitled under this Agreement, such amounts shall be paid
in a lump sum to one or more beneficiaries designated in writing by Executive
(each, a "Beneficiary"). If none is so designated, the Executive's estate shall
be his or her Beneficiary.

      11.5 Non-Alienation of Benefits. Benefits payable under this Agreement
shall not be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, charge, garnishment, execution or levy of any
kind, either voluntary or involuntary, before actually being received by
Executive, and any such attempt to dispose of any right to benefits payable
under this Agreement shall be void.

      11.6 Severability. If any one or more Articles, Sections or other portions
of this Agreement are declared by any court or governmental authority to be
unlawful or invalid, such unlawfulness or invalidity shall not serve to
invalidate any Article, Section or other portion not so declared to be unlawful
or invalid. Any Article, Section or other portion so declared to be unlawful or
invalid shall be construed so as to effectuate the terms of such Article,
Section or other portion to the fullest extent possible while remaining lawful
and valid.

written instrument executed by the Company and Executive.

                               EXELON CORPORATION

                    CHANGE-IN-CONTROL EMPLOYMENT AGREEMENT


      THIS AGREEMENT dated as of June 1, 2001 (the "Agreement Date") is made by
and among Exelon Corporation, incorporated under the laws of the Commonwealth of
Pennsylvania (together with successors thereto, the "Company"),
_____________________, a _______________ corporation (together with successors
thereto, the "Subsidiary"), and _____________________ ("Executive").

                                    RECITALS

      The Board of Directors of the Company (the "Board") has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued services of the Executive, despite the
possibility or occurrence of a Change in Control of the Company. The Board
believes it is imperative to reduce the distraction of the Executive that would
result from the personal uncertainties caused by a pending or threatened Change
in Control or a Significant Acquisition, to encourage the Executive's full
attention and dedication to the Company, and to provide the Executive with
compensation and benefits arrangements upon a Change in Control which are
competitive with those of similarly-situated corporations. This Agreement is
intended to accomplish these objectives.

                                   ARTICLE I.

                                   DEFINITIONS

      As used in this Agreement, the terms specified below shall have the
following meanings:

      1.1 "Accrued Annual Incentive" means the amount of any Annual Incentive
earned but not yet paid with respect to the Company's latest fiscal year ended
prior to the Termination Date.

      1.2 "Accrued Base Salary" means the amount of Executive's Base Salary that
is accrued but not yet paid as of the Termination Date.

      1.3 "Accrued LTIP Award" means the amount of any LTIP Award earned and
vested, but either deferred or not yet paid as of the Termination Date.

      1.4 "Accrued Obligations" means, as of any date, the sum of Executive's
Accrued Base Salary, Accrued Annual Incentive, Accrued LTIP Award, any accrued
but unpaid paid time off, and any other amounts and benefits which are then due
to be paid or provided to Executive by the Company, but have not yet been paid
or provided (as applicable).

      1.5 "Affiliate" means any Person (including the Subsidiary) that directly
or indirectly controls, is controlled by, or is under common control with, the
Company. For purposes of this definition the term "control" with respect to any
Person means the power to direct or cause the direction of management or
policies of such Person, directly or indirectly, whether through the ownership
of Voting Securities, by contract or otherwise.
<PAGE>
      1.6 "Agreement Date" -- see the introductory paragraph of this Agreement.

      1.7 "Agreement Term" means the period commencing on the Agreement Date and
ending on the second anniversary of the Agreement Date or, if later, such later
date to which the Agreement Term is extended under the following sentence unless
earlier terminated as provided herein. Commencing on the first anniversary of
the Agreement Date, the Agreement Term shall automatically be extended each day
by one day to create a new two-year term until, at any time after the first
anniversary of the Agreement Date, the Company delivers written notice (an
"Expiration Notice") to Executive that the Agreement shall expire on a date
specified in the Expiration Notice (the "Expiration Date") that is not less than
12 months after the date the Expiration Notice is delivered to Executive;
provided, however, that if a Change Date, Imminent Control Change,
Disaggregation or Significant Acquisition occurs before the Expiration Date
specified in the Expiration Notice, then such Expiration Notice shall be void
and of no further effect. If such Imminent Control Change or Disaggregation does
not culminate in a Change Date, then such Expiration Notice shall be reinstated
and the Agreement shall expire on the date originally specified as the
Expiration Date, or if later, the date the Imminent Control Change lapses or the
end of the sixtieth day after the Disaggregation. Notwithstanding anything
herein to the contrary, the Agreement Term shall end at the end of the Severance
Period if applicable, or if there is no Severance Period, the earliest of the
following: (a) the second anniversary of the Change Date, (b) eighteen (18)
months after the Significant Acquisition provided there has been no Change Date,
(c) the end of the sixtieth day after the Disaggregation if there has been no
Change Date after the Disaggregation, or (d) the Termination Date.

      1.8   "Annual Incentive" -- see Section 2.8.

            (a)   the Change Date with respect to the Post-Change Period;

from such location (unless such other location is closer to Executive's
residence than the prior location); provided, however, that in determining
whether the Executive's Termination of Employment is for Cause, "Cause" shall be
determined as though the provisions of Section 3.3(a) applied commencing with
the first day of the Post-Disaggregation Period.

      2.5 Executive's Obligations. During the Executive's employment, (other
than any periods of paid time off, sick leave or disability to which Executive
is entitled), Executive agrees to devote Executive's full attention and time to
the business and affairs of the Company (or, in the case of a Disaggregation,
the Disaggregated Entity) and to use Executive's best efforts to perform such
duties. Executive may (i) serve on corporate, civic or charitable boards or
committees, (ii) deliver lectures, fulfill speaking engagements or teach at
educational institutions and (iii) manage personal investments, so long as such
activities are consistent with the Plans of the Employer (or in the case of a
Disaggregation, the Disaggregated Entity) in effect from time to time, and do
not significantly interfere with the performance of Executive's duties under
this Agreement.

      2.6   Base Salary During the Post-Change Period.

            (a) Base Salary During the Post-Change Period. Prior to the
      Termination Date during the Post-Change Period, the Company shall pay or
      cause to be paid to Executive an annual base salary in cash, which shall
      be paid in a manner consistent with the Employer's payroll practices in
      effect immediately before the Applicable Trigger Date at an annual rate
      not less than 12 times the highest monthly base salary paid or payable to
      Executive by the Employer in respect of the 12-month period immediately
      before the Applicable Trigger Date (such annual rate salary, the "Base
      Salary"). During the Post-Change Period, the Base Salary shall be reviewed
      no more than 12 months after the last salary increase awarded to Executive
      prior to the Applicable Trigger Date and thereafter shall be reviewed and
      shall be increased at any time and from time to time as


                                       11
<PAGE>
      shall be substantially consistent with increases in base salary awarded to
      peer executives of the Company generally. Base Salary shall not be reduced
      after any such increase unless such reduction is part of a policy, program
      or arrangement applicable to peer executives of the Company, and the term
      Base Salary as used in this Agreement shall refer to Base Salary as so
      increased. Any increase in Base Salary shall not limit or reduce any other
      obligation of the Company to the Executive under this Agreement.

            (b) Base Salary During the Imminent Control Change Period,
      Post-Significant Acquisition Period and Post-Disaggregation Period.
      Section 2.7(a) shall not apply during the Imminent Control Change Period,
      Post-Significant Acquisition Period or Post-Disaggregation Period.

      2.7   Annual Incentive.

            (a) Annual Incentive During the Post-Change Period. In addition to
      Base Salary, the Company shall provide or cause to be provided to
      Executive the opportunity to receive payment of an annual incentive (the
      "Annual Incentive") with an award opportunity no less, including target
      performance goals not materially more difficult to achieve, than that in
      effect immediately prior to the Applicable Trigger Date for each
      applicable performance period which commences prior to the Termination
      Date and ends during the Post-Change Period.

            (b) Annual Incentive during the Imminent Control Change Period,
      Post-Significant Acquisition Period or Post-Disaggregation Period. Section
      2.8(a) shall not apply during the Imminent Control Change Period,
      Post-Significant Acquisition Period or Post-Disaggregation Period.

      2.8   Other Compensation and Benefits.

            (a) Other Compensation and Benefits during the Post-Change Period.
      In addition to Base Salary and Annual Incentive, prior to the Termination
      Date the Company shall provide or cause to be provided, throughout the
      Post-Change Period, the following other compensation and benefits to
      Executive, provided that, in no event shall such additional compensation
      and benefits (including incentives, measured with respect to long term and
      special incentives, to the extent, if any, that such distinctions are
      applicable) be materially less favorable, in the aggregate, than the
      greater of (A) those provided by the Employer for the Executive (including
      any such compensation and benefits provided under Plans) as in effect at
      any time during the 90-day period immediately preceding the Applicable
      Trigger Date, or (B) those provided at any time after the Applicable
      Trigger Date to peer executives of the Company generally:

                  (i)   Incentive, Savings and Retirement Plans.  Executive
            shall be entitled to participate in all incentive, savings and
            retirement Plans applicable to peer executives of the Company
            generally.

                  (ii) Welfare Benefit Plans. Executive and/or the Executive's
            family, as the case may be, shall be eligible for participation in
            and shall receive all benefits under welfare benefit Plans ("Welfare
            Plans") (including medical, prescription, dental, disability,
            employee life, group life, accidental death


                                       12

            and travel accident insurance benefits, but excluding any severance
            pay) provided by the Employer from time to time to peer executives
            of the Company generally.

                  (iii) Other Employee Benefits. Executive shall be entitled to
            other employee benefits, perquisites and fringe benefits in
            accordance with the most favorable Plans applicable to peer
            executives of the Company generally.

                  (iv) Expenses. Executive shall be entitled to receive prompt
            reimbursement for all reasonable business expenses incurred by the
            Executive in accordance with the most favorable Plans applicable to
            peer executives of the Company generally.

                  (v) Office and Support Staff. Executive shall be entitled to
            an office or offices of a size and with furnishings and other
            appointments, and to secretarial and other assistance substantially
            equivalent to the office or offices, furnishings, appointments and
            assistance as in effect with respect to Executive on the Applicable
            Trigger Date.

                  (vi)  Paid Time Off.  Executive shall be entitled to paid
            time off in accordance with the Plans applicable to peer
            executives of the Company generally.

                  (vii) LTIP Awards. Awards under the LTIP shall be granted to
            Executive with aggregate target opportunities (including target
            performance goals not materially more difficult to achieve) no less
            than the average of the Executive's awards (expressed as a
            percentage of Executive's Base Salary in effect at the beginning of
            the applicable performance period) granted in the three-year period
            ending on the Applicable Trigger Date.

            (b) Other Compensation and Benefits During the Imminent Control
      Change Period, Post-Significant Acquisition Period or Post-Disaggregation
      Period. Section 2.9(a) shall not apply during an Imminent Control Change
      Period, Post-Significant Acquisition Period or Post-Disaggregation Period.

            (c)   Stock Options, Restricted Stock, and Performance Shares
      During the Post-Disaggregation Period.

                  (i)   Stock Options.

                              (A) Extinguished or Converted at Disaggregation.
                        If so provided in the documents and instruments
                        ("Disaggregation Documents") pursuant to which the
                        Disaggregation is effected, then all of Executive's
                        Stock Options shall (I) be extinguished immediately
                        prior to the Disaggregation for such consideration as is
                        provided for in the Disaggregation Documents (but not
                        less than the product of the number of Executive's
                        vested Stock Options multiplied by the difference
                        between the fair market value of Exelon stock
                        immediately prior to the Disaggregation and the option
                        exercise price), or (II) be converted into options to
                        acquire

                        stock of the Disaggregated Entity or an affiliate
                        thereof on a basis determined by the Company in good
                        faith to preserve economic value.

                              (B) Extinguished or Converted at Merger. If the
                        Change in Control following the Disaggregation is a
                        Merger, and if so provided in the agreement pursuant to
                        which the Merger is effected, then all of Executive's
                        Company Stock Options that were not extinguished or

                        of peer executives employed by the Company or an
                        Affiliate, or (II) be converted into options to acquire
                        stock of the corporation resulting from the Merger
                        ("Merger Survivor") or an affiliate thereof, on the same
                        basis as Stock Options of employees of the Company are
                        converted.

                              (C) Stock Options after the Disaggregation.
                        Executive's unextinguished Stock Options, whether or not
                        they are converted to options for stock of the
                        Disaggregated Entity or Merger Survivor, shall continue
                        to vest and, once vested, shall remain exercisable in
                        accordance with their terms, subject to Section 4.3(b).

                  (ii)  Performance Shares.

                        If so provided in the Disaggregation Documents, all of
                        Executive's Performance Shares shall (I) be extinguished
                        immediately prior to the Disaggregation for such
                        consideration as is provided under the Disaggregation
                        Documents (but no less than the fair market value,
                        immediately prior to the Disaggregation, of a number of
                        Exelon shares equal to the sum of Executive's earned and
                        awarded Performance Shares and the target number of
                        Executive's Performance Shares that have not yet been
                        earned and awarded), or (II) shall be converted into
                        performance shares with respect to the Disaggregated
                        Entity or an affiliate (on a basis determined by the
                        Company in good faith to preserve economic value for the
                        Executive).

                              (B) Extinguished or Converted at Merger. If the
                        Change in Control following the Disaggregation is a
                        Merger, and if so provided in the agreement pursuant to
                        which the Merger is effected, then all of Executive's

                        Entity or an affiliate shall (I) be extinguished
                        immediately prior to the Change in Control for such

                        or an affiliate thereof, on the same basis as
                        Performance Shares of employees of the Company are
                        converted.

                              (C) Performance Shares after the Disaggregation.
                        Executive's unextinguished Performance Shares, whether

                        Disaggregated Entity or Merger Survivor, will continue
                        to vest during the Post-Disaggregation Period, subject
                        to Section 4.3(c).

                        which the Merger is effected, then all of Executive's
                        Restricted Stock that was not extinguished or converted

                        converted into restricted stock of the Merger Survivor
                        or an affiliate thereof, and such converted restricted
                        stock will continue to vest during the
                        Post-Disaggregation Period prior to the Termination
                        Date.

                              (C) Restricted Stock after the Disaggregation.
                        Executive's unextinguished Restricted Stock, whether or

                                  ARTICLE III.

                            TERMINATION OF EMPLOYMENT

      3.1   Disability.

            (a) During the Agreement Term, the Employer (or, if applicable, the
      Disaggregated Entity) may terminate Executive's employment at any time
      because of


                                       15
<PAGE>
      Executive's Disability by giving Executive or his legal representative, as
      applicable, (i) written notice in accordance with Section 11.8 of the
      Company's intention to terminate Executive's employment pursuant to this
      Section and (ii) a certification of Executive's Disability by a physician
      selected by the Employer or its insurers, subject to the reasonable
      consent of Executive or Executive's legal representative, which consent
      shall not be unreasonably withheld or delayed. Executive's employment
      shall terminate effective on the 30th day after Executive's receipt of
      such notice (which such 30th day shall be deemed to be the "Disability
      Effective Date") unless, before such 30th day, Executive shall have
      resumed the full-time performance of Executive's duties.

            (b) "Disability" means any medically determinable physical or mental
      impairment that has lasted for a continuous period of not less than six
      months and can be expected to be permanent or of indefinite duration, and
      that renders Executive unable to perform the duties required under this
      Agreement.

      3.2   Death.  Executive's employment shall terminate automatically upon
Executive's death during the Agreement Term.

      3.3   Termination by the Company for Cause.

            (a) Termination for Cause During the Post-Change Period and
      Post-Disaggregation Period. During the Post-Change Period, the Company may
      terminate Executive's employment (or cause Executive's employment to be
      terminated) for Cause solely in accordance with all of the substantive and
      procedural provisions of this Section 3.3(a).

                  (i) Definition of Cause. For a Termination of Employment for
            Cause for which the Notice of Termination is given during the
            Post-Change Period or the Post-Disaggregation Period, "Cause" means
            any one or more of the following:

                        (1) the Executive's willful commission of acts or
                  omissions which have, have had, or are likely to have a
                  material adverse effect on the business, operations, financial
                  condition or reputation of the Company or an Affiliate;

                        (2) the Executive's conviction (including a plea of
                  guilty or nolo contendere) of a felony or any crime of fraud,
                  theft, dishonesty or moral turpitude; or

                        (3) the Executive's material violation of any statutory
                  or common law duty of loyalty to the Company or an Affiliate.

                  For purposes of this Section, no act, or failure to act, on
            the part of the Executive shall be considered "willful" unless it is
            done, or omitted to be done, by the Executive in bad faith or
            without reasonable belief that the Executive's action or omission
            was in the best interests of the Company. Any act, or failure to
            act, based upon authority given pursuant to a resolution duly
            adopted by the Board or upon the instructions of the chief executive
            officer or a senior officer of the Company other than Executive, or
            based upon the advice of counsel for the


                                       16
<PAGE>
            Company shall be conclusively presumed to be done, or omitted to be
            done, by the Executive in good faith and in the best interests of
            the Company.

                  (ii) Procedural Requirements for Termination for Cause. The
            Executive's Termination of Employment shall not be deemed to be for
            Cause under this Section 3.3(a) unless and until there shall have
            been delivered to the Executive a copy of a resolution duly adopted
            by the affirmative vote of not less than 60% of the entire
            membership of the Board at a meeting of such Board called and held
            for such purpose (after reasonable written notice of such meeting is
            provided to the Executive and the Executive is given an opportunity,
            together with counsel, to be heard before the Board), finding that,
            in the good faith opinion of the Board, the Executive's acts, or
            failure to act, constitutes Cause and specifying the particulars
            thereof in detail.

                  (iii) Post-Disaggregation Period. In the event Executive's
            Termination of Employment is from a Disaggregated Entity in a
            Post-Disaggregation Period, the definition of Cause and the
            procedural requirements for termination for Cause in this Section
            3.3(a) shall be applied by substituting "Disaggregated Entity" for
            "Company," "affiliate of the Disaggregated Entity" for "Affiliate,"
            and "Disaggregated Entity's Board" for "Board." Further, the Company
            shall have no obligation to provide payments or benefits under
            Section 4.3 if the Board determines that the Company could have
            terminated Executive's employment for Cause as defined above in
            Section 3.3(a)(i)(1), if the Executive had been employed by the
            Company, such determination by the Board to be made as provided in
            Section 3.3(a)(ii) but applying the flush language at the end of
            Section 3.3(a)(i) by substituting "Disaggregated Entity" for
            "Company" and the "Disaggregated Entity's Board" for "Board."

            (b) Termination for Cause During the Imminent Control Change Period
      or Post-Significant Acquisition Period. During the Imminent Control Change
      Period and any Post-Significant Acquisition Period, the Company may
      terminate Executive's employment (or cause Executive's employment to be
      terminated) for Cause solely in accordance with all of the substantive and
      procedural provisions of this Section 3.3(b).

                  (i) Definition of Cause. For a Termination of Employment for
            Cause for which the Notice of Termination is given during the
            Imminent Control Change Period or Post-Significant Acquisition
            Period, "Cause" means any one or more of the following:

                        (1) the Executive's willful commission of acts or
                  omissions which have, have had, or are likely to have a
                  material adverse effect on the business, operations, financial
                  condition or reputation of the Company or an Affiliate;

                        (2) the Executive's conviction (including a plea of
                  guilty or nolo contendere) of a felony or any crime of fraud,
                  theft, dishonesty or moral turpitude;


                                       17
<PAGE>
                        (3)   the Executive's material violation of any
                  statutory or common law duty of loyalty to the Company or
                  an Affiliate; or

                        (4) Executive's failure to meet objective performance
                  criteria of the position, provided that, in the case of a
                  Termination of Employment during an Imminent Control Change
                  Period (other than after a Disaggregation) this Section
                  3.3(b)(i)(4) shall be inapplicable if the Imminent Change in
                  Control culminates in a Change Date.

                  For purposes of this Section, no act, or failure to act, on
            the part of the Executive shall be considered "willful" unless it is
            done, or omitted to be done, by the Executive in bad faith or
            without reasonable belief that the Executive's action or omission
            was in the best interests of the Company. Any act, or failure to
            act, based upon authority given pursuant to a resolution duly
            adopted by the Board or upon the instructions of the chief executive
            officer or a senior officer of the Company other than Executive, or
            based upon the advice of counsel for the Company shall be
            conclusively presumed to be done, or omitted to be done, by the
            Executive in good faith and in the best interests of the Company.
                  (ii) Procedural Requirements for Termination for Cause. The
            Executive's Termination of Employment shall not be deemed to be for
            Cause under this Section 3.3(b) unless and until there shall have
            been delivered to the Executive a copy of a resolution duly adopted
            by the affirmative vote of not less than a majority of the entire
            membership of the Board, finding that the Executive's acts or
            failure to act, constitute Cause and specifying the particulars
            thereof in detail. Executive shall receive advance notice of such
            vote of the Board, but shall not have the right to appear in person
            or by counsel before the Board.

      3.4 Termination by the Executive for Good Reason. During the Post-Change
Period, an Imminent Control Change Period, a Post-Significant Acquisition Period
or Post-Disaggregation Period, Executive may terminate his or her employment for
Good Reason in accordance with the substantive and procedural provisions of this
Section 3.4.

            (a) Definition of Good Reason. For purposes of this Section 3.4(a),
      and subject to the provisions of subsections (b) through (e), "Good
      Reason" means the occurrence of any one or more of the following actions
      or omissions prior to the Termination Date during the Post-Change Period,
      the Imminent Control Change Period, the Post-Significant Acquisition
      Period or the Post-Disaggregation Period:

                  (i) a material adverse reduction in the nature or scope of the
            Executive's office, position, duties, functions, responsibilities or
            authority (other than in a Post-Significant Acquisition Period);

                  (ii) a material reduction of the Executive's salary, incentive
            compensation or aggregate benefits unless such reduction is part of
            a policy, program or arrangement applicable to peer executives of
            the Company and of any successor entity;


                                       18
<PAGE>
                  (iii) the failure of any successor to the Company to assume
            this Agreement;

                  (iv) a relocation (other than in a Post-Significant
            Acquisition Period), of more than 50 miles of (i) the Executive's
            workplace, or (ii) the principal offices of the Company or its
            successor (if such offices are the Executive's workplace), in each
            case without the consent of the Executive; provided, however, in
            both cases of (i) and (ii) of this Section 3.4(a), such new location
            is farther from Executive's residence that the prior location;

                  (v) a requirement (other than in a Post-Significant
            Acquisition Period) of the greater of (i) more than 24 days of
            travel per year, or (ii) at least 20% more business travel than was
            required of the Executive prior to the Applicable Trigger Date;

                  (vi) any failure by the Company to comply with any of the
            provisions of Sections 2.7, 2.8 and 2.9 of this Agreement, other
            than an isolated, insubstantial and inadvertent failure not
            occurring in bad faith and which is remedied by the Company promptly
            after receipt of notice thereof given by the Executive; or

                  (vii) a material breach of this Agreement by the Company or
            its successor;

      provided that the occurrence of a Disaggregation shall not be Good Reason
      if the Executive retains substantially the same position (determined
      without regard to reporting requirements) with the Disaggregated Entity,
      with substantially the same compensation and benefits in the aggregate, as
      immediately prior to such Disaggregation, notwithstanding Sections
      3.4(a)(i), 3.4(a)(ii) and 3.4(a)(vi).

            (b) Application of "Good Reason" Definition During the Imminent
      Control Change Period. During the Imminent Control Change Period, "Good
      Reason" shall not include the events or conditions described in Section
      3.4(a)(i), 3.4(a)(iv) or 3.4(a)(v) unless the Imminent Control Change
      Period culminates in a Change Date. Further, if Executive's Termination of
      Employment occurs during an Imminent Control Change Period that culminates
      in a Change Date, then, except as provided in Section 3.4(c), the
      definition of "Good Reason" shall be applied as though Sections 2.1,
      2.6(a), 2.7(a) and 2.8(a) were applicable during the Imminent Control
      Change Period prior to the Executive's Termination of Employment.

            (c) Special Conditions Relating to Good Reason During the
      Post-Disaggregation Period. If Executive retains substantially the same
      position with the Disaggregated Entity as immediately prior to the
      Disaggregation (determined without regard to reporting requirements), then
      (1) Section 3.4(a)(i) shall apply only with respect to the Executive's
      office, duties, functions, responsibilities or authority as in effect at
      the Disaggregated Entity on the day following the Disaggregation, (2)
      subsections 3.4(a)(iv) and 3.4(a)(v) shall apply only with respect to
      relocations or travel required more than 60 days after the Disaggregation
      and shall be applied by substituting "Disaggregated Entity"


                                       19
<PAGE>
      for "any successor to the Company", and (3) all references in Section 3.4
      to the Company or its successor shall be to the Disaggregated Entity or
      its successor.

            (d) Limitations on Good Reason. Notwithstanding the foregoing
      provisions of this Section 3.4, no act or omission shall constitute a
      material breach of this Agreement by the Company, nor grounds for "Good
      Reason":

                  (i) unless the Executive gives the Company and the Employer 30
            days' prior notice of such act or omission and the Company fails to
            cure such act or omission within the 30-day period;

                  (ii) if the Executive first acquired knowledge of such act or
            omission more than 12 months before the Executive gives the Company
            and the Employer such notice; or

                  (iii) if the Executive has consented in writing to such act or
            omission in a document that makes specific reference to this
            Section.

            (e) Notice by Executive. In the event of any Termination of
      Employment by Executive for Good Reason, Executive shall as soon as
      practicable thereafter notify the Company and the Employer (and
      Disaggregated Entity, if applicable) of the events constituting such Good
      Reason by a Notice of Termination. Subject to the limitations in Section
      3.4(d), a delay in the delivery of such Notice of Termination shall not
      waive any right of Executive under this Agreement.

                                   ARTICLE IV.

        COMPANY'S OBLIGATIONS UPON CERTAIN TERMINATIONS OF EMPLOYMENT

      4.1 Termination During the Post-Change Period or Post-Significant
Acquisition Period. If, during the Post-Change Period or Post-Significant
Acquisition Period (other than any portion of any such periods that are also a
Post-Disaggregation Period), the Employer terminates Executive's employment
other than for Cause or Disability, or Executive terminates employment for Good
Reason, the Company's sole obligations to Executive under Articles II and IV
shall be as set forth in this Section 4.1.

            (a) Termination during the Post-Change Period or Post-Significant

                  (iii) Deferred Compensation and Non Qualified Defined
            Contribution Plans. All amounts previously deferred by, or accrued

            Corporation Deferred Stock Plan, or any successor of either of them,
            or under any non-qualified defined contribution or deferred
            compensation plan of the Company or an Affiliate (unless Executive
            has made an irrevocable election in writing, filed with the Company
            no more than 60 days after the Applicable Trigger Date (or such
            earlier date as counsel to the Company may deem to be required to
            avoid constructive receipt of such amounts), and in any event at
            least 90 days prior to the Termination Date to have such amounts
            paid under the terms of the Exelon Corporation Deferred Compensation
            Plan or the Exelon Corporation Deferred Stock Plan, as applicable,
            or any successor of either (including any elections in effect
            thereunder)) whether vested or unvested, together with any accrued
            earnings thereon, to the extent that such amounts and earnings have
            not been previously paid by the Employer and are not provided under
            the terms of either such non-qualified plan;

                  (iv)  Pension Enhancements.  An amount equal to the
            positive difference, if any, between

                        (1)   the lump sum value of Executive's benefit under
                  the SERP, calculated as if Executive had

                              (A)   become fully vested in all benefits,

                              (B) attained as of the Termination Date an age
                        that is [THREE/TWO AND ONE-HALF] years greater than
                        Executive's actual age,

                              (C) accrued a number of years of service (for
                        purposes of determining the amount of such benefits,
                        entitlement to - but not commencement of - early
                        retirement benefits, and all other purposes of such
                        defined benefit plans) that is [THREE/TWO AND ONE-HALF]
                        years greater than the number of years of service
                        actually accrued by Executive as of the Termination Date
                        and that includes the number of years of service
                        credited to Executive pursuant to [ANY OTHER AGREEMENT
                        BETWEEN THE COMPANY AND THE EXECUTIVE/SPECIFY
                        AGREEMENT], and

                              (D) received the severance benefits specified in
                        Sections 4.1(a)(ii) and 4.1(a)(vi) as covered
                        compensation in equal monthly installments during the
                        Severance Period,

                        minus

                        (2)   the aggregate amounts paid or payable to
                  Executive under the SERP.

                  (v) Unvested Benefits Under Defined Benefit Plan. To the
            extent not paid pursuant to clause (iii) or (iv) of this Section
            4.1(a), an amount equal to the actuarial equivalent present value of
            the unvested portion of Executive's accounts or accrued benefits
            under any tax-qualified (under Section 401(a) of the Code)


                                       21
<PAGE>
            defined benefit retirement plan maintained by the Employer as of the
            Termination Date and forfeited by Executive by reason of the
            Termination of Employment; and

                  (vi)  Multiple of Salary and Severance Incentive.  An
            amount equal to [THREE (3.0)/TWO AND ONE-HALF (2.5)] times the
            sum of (x) Base Salary plus (y) the Severance Incentive.

            (b) Termination during the Post-Change Period or Post-Significant
      Acquisition Period: Stock Options. Each of the Executive's stock options,
      stock appreciation rights or similar incentive awards granted under the
      LTIP ("Stock Options") shall (i) become fully vested, and (ii) remain
      exercisable until (1) the option expiration date for any such Stock
      Options granted prior to January 1, 2002 or (2) the fifth anniversary of
      the Termination Date or, if earlier, the option expiration date for any
      such Stock Options granted on or after January 1, 2002.

            (c) Termination during the Post-Change Period or Post-Significant
      Acquisition Period: LTIP Vesting. On the Termination Date all of the
      performance shares, performance units or similar stock incentive awards
      granted to the Executive under the Exelon Performance Share Program under
      the LTIP ("Performance Shares") to the extent earned by and awarded to the
      Executive (i.e. as to which the first year of the performance cycle has
      elapsed) as of the Termination Date, shall become fully vested at the
      actual level earned and awarded, and, to the extent not yet earned by and
      awarded to the Executive (i.e. as to which the first year of the
      performance cycle has not elapsed) as of the Termination Date, shall
      become fully vested at the LTIP Target Level.

            (d) Termination During the Post-Change Period or Post-Significant
      Acquisition Period: Other Restricted Stock. All forfeiture conditions that
      as of the Termination Date are applicable to any deferred stock unit,
      restricted stock or restricted share units awarded to the Executive by the
      Company other than under the Exelon Performance Share Program under the
      LTIP ("Restricted Stock") shall lapse immediately and all such awards will
      become fully vested, and within ten business days after the Termination
      Date, the Company shall deliver to Executive all of such shares
      theretofore held by or on behalf of the Company.

            (e) Termination During the Post-Change Period or Post-Significant
      Acquisition Period: Continuation of Welfare Benefits. During the Severance
      Period (and continuing through such later date as any Welfare Plan may
      specify), the Company shall continue to provide (or shall cause the
      continued provision) to Executive and Executive's family welfare benefits
      under the Welfare Plans to the same extent as if Executive had remained
      employed during the Severance Period. Such provision of welfare benefits
      shall be subject to the following:

                  (i) In determining benefits applicable under such Welfare
            Plans, the Executive's annual compensation attributable to base
            salary and incentives for any plan year or calendar year, as
            applicable, shall be deemed to be not less than the Executive's Base
            Salary and Annual Incentive.


                                       22
<PAGE>
                  (ii) The cost of such welfare benefits to Executive and family
            under this Section 4.1(e) shall not exceed the cost of such benefits
            to peer executives who are actively employed after the Termination
            Date.

                  (iii) The Executive's rights under this Section 4.1(e) shall
            be in addition to and not in lieu of any post-termination
            continuation coverage or conversion rights the Executive may have
            pursuant to applicable law, including, without limitation,
            continuation coverage required by Section 4980B of the Code.

                  (iv) If the Executive has, as of the last day of the Severance
            Period, attained age 50 and completed at least 10 years of service,
            the Executive shall be entitled to the retiree benefits provided
            under any Welfare Plan of the Company; provided, however, that for
            purposes hereof, any years of credited service granted to the
            Executive [IN ANY OTHER PLAN OR AGREEMENT BETWEEN EXECUTIVE AND THE
            COMPANY/SPECIFY AGREEMENT] shall be taken into account. For purposes
            of determining eligibility for (but not the time of commencement of)
            such retiree benefits, the Executive shall also be considered (1) to
            have remained employed until the last day of the Severance Period
            and to have retired on the last day of such period, and (2) to have
            attained at least the age the Executive would have attained on the
            last day of the Severance Period.

      Notwithstanding the foregoing, if the Executive obtains a specific type of
      coverage under welfare plan(s) sponsored by another employer of Executive
      (e.g. medical, prescription, vision, dental, disability, individual life
      insurance benefits, group life insurance benefits, but excluding for the
      purposes of this sentence retiree benefits if Executive is so eligible),
      then the Company shall not be obligated to provide any such specific type
      of coverage.

            (f) Termination during the Post-Change Period or Post-Significant
      Acquisition Period: Outplacement. To the extent actually incurred by
      Executive, the Company shall pay or cause to be paid on behalf of
      Executive, as incurred, all reasonable fees and costs charged by a
      nationally recognized outplacement firm selected by the Executive for
      outplacement services provided up to 12 months after the Termination Date.
      No cash shall be paid in lieu of such fees and costs.

            (g) Termination during the Post-Change Period or Post-Significant
      Acquisition Period: Indemnification. The Executive shall be indemnified
      and held harmless by the Company to the greatest extent permitted under
      applicable law as the same now exists or may hereafter be amended (but, in
      the case of any such amendment, only to the extent that such amendment
      permits the Company to provide broader indemnification than was permitted
      prior to such amendment) and the Company's by-laws as such exist on the
      Agreement Date if the Executive was, is, or is threatened to be, made a
      party to any pending, completed or threatened action, suit, arbitration,
      alternate dispute resolution mechanism, investigation, administrative
      hearing or any other proceeding whether civil, criminal, administrative or
      investigative, and whether formal or informal, by reason of the fact that
      the Executive is or was, or had agreed to become, a director, officer,
      employee, agent, or fiduciary of the Company or any other entity which the
      Executive is or was serving at the request of the Company ("Proceeding"),
      against all expenses (including all reasonable attorneys' fees) and all
      claims, damages, liabilities and losses incurred or suffered by the
      Executive or to which the Executive may become


                                       23
<PAGE>
      subject for any reason. A Proceeding shall not include any proceeding to
      the extent it concerns or relates to a matter described in Section 6.1(a)
      (concerning reimbursement of certain costs and expenses). Upon receipt
      from Executive of (i) a written request for an advancement of expenses,
      which Executive reasonably believes will be subject to indemnification
      hereunder and (ii) a written undertaking by Executive to repay any such
      amounts if it shall ultimately be determined that Executive is not
      entitled to indemnification under this Agreement or otherwise, the Company
      shall advance such expenses to Executive or pay such expenses for
      Executive, all in advance of the final disposition of any such matter.

            (h) Termination during the Post-Change Period or Post-Significant
      Acquisition Period: Directors' and Officers' Liability Insurance. For a
      period of six years after the Termination Date (or for any known longer
      applicable statute of limitations period), the Company shall provide
      Executive with coverage under a directors' and officers' liability
      insurance policy in an amount no less than, and on terms no less favorable
      than, those provided to senior executive officers and directors of the
      Company on the Applicable Trigger Date.

      4.2 Termination During an Imminent Control Change Period. If, during an
Imminent Control Change Period, Executive has a Termination of Employment that
would entitle Executive to benefits under the Exelon Corporation Key Management
Severance Plan or its successor, then the Company shall, prior to the occurrence
of a Change Date, provide Executive any benefits to which Executive may be
entitled under the Exelon Corporation Key Management Severance Plan or its
successor. If, during an Imminent Control Change Period, the Employer terminates
Executive's employment other than for Disability and other than for a reason
that would constitute Cause as defined in Section 3.3(b) or if Executive
terminates employment for a reason that would constitute Good Reason as defined
in Section 3.4(b), then subject to the preceding sentence, unless such
Termination of Employment occurred during the Post-Significant Acquisition
Period, the Company's sole obligations to Executive under Articles II and IV
shall be as set forth in this Section 4.2. The Company's obligations to
Executive under this Section 4.2 shall be reduced by any amounts or benefits
paid or provided pursuant to the Exelon Corporation Key Management Severance
Plan or any successor thereto. If Executive's Termination of Employment occurred
during any portion of an Imminent Control Change Period that is also a
Post-Significant Acquisition Period, the Company's obligations to Executive, if
any, shall be determined under Section 4.1.

            (a) Termination During an Imminent Control Change Period: Cash
      Severance Payments. If the Imminent Control Change Period culminates in a
      Change Date, the Company shall pay (or cause to be paid) to Executive, a
      lump-sum cash amount, within thirty business days after the later of the
      Termination Date or the Change Date, equal to the sum of all amounts
      described in Section 4.1(a)(i) through (v). The amount described in
      Section 4.1(a)(vi) shall be paid to Executive as described in Section 4.4,
      provided that amounts that would have been paid prior to the Change Date
      shall be paid in a lump sum (without interest) within 30 business days
      after the Change Date.

            (b)   Termination During an Imminent Control Change Period:
      Vested Stock Options.  Executive's Stock Options, to the extent vested
      on the Termination Date,

                  (i) will not expire (unless such Stock Options would have
            expired had Executive remained an employee of the Company) during
            the Imminent Control Change Period; and

                  (ii) will continue to be exercisable after the Termination
            Date to the extent provided in the applicable grant agreement or
            Plan, and thereafter, such Stock Options shall not be exercisable
            during the Imminent Control Change Period.

      If the Imminent Control Change Period lapses without a Change Date, then
      Executive's Stock Options, to the extent vested on the Termination Date,
      may be exercised, in whole or in part, during the 30-day period following
      the lapse of the Imminent Control Change, or, if larger, the period during
      which Executive's vested Stock Options could otherwise be exercised under
      the terms of the applicable grant agreement or Plan, (but in no case shall
      any Stock Options remain exercisable after the date on which such Stock
      Options would have expired if Executive had remained an employee of the
      Company).
      If the Imminent Control Change Period culminates in a Change Date, then
      effective upon the Change Date, Executive's Stock Options, to the extent
      vested on the Termination Date, may be exercised in whole or in part by
      the Executive at any time until (1) the option expiration date for such
      Stock Options granted prior to January 1, 2002 or (2) the earlier of the
      fifth anniversary of the Change Date or the option expiration date for
      such Stock Options granted on or after January 1, 2002.

            (c)   Termination During an Imminent Control Change Period:
      Unvested Stock Options.  Executive's Stock Options that are not vested
      on the Termination Date

                  (i) will not expire (unless such Stock Options would have
            expired had Executive remained an employee of the Company) during
            the Imminent Control Change Period; and

                  (ii) will not continue to vest and will not be exercisable
            during the Imminent Control Change Period after the expiration of
            the period for post-termination exercise under the terms of the
            applicable Stock Option Agreement.

      If the Imminent Control Change lapses without a Change Date, such unvested
      Stock Options will thereupon expire.

      If the Imminent Control Change culminates in a Change Date, then
      immediately prior to the Change Date, such unvested Stock Options shall
      become fully vested, and may thereupon be exercised in whole or in part by
      the Executive at any time until (1) the option expiration date for such
      Stock Options granted prior to January 1, 2002 or (2) the earlier of the
      fifth anniversary of the Change Date, or the option expiration date for
      such Stock Options granted on or after January 1, 2002.

            (d) Termination During an Imminent Control Change Period:
      Performance Shares. Executive's Performance Shares granted under the
      Exelon Performance Share Program under the LTIP will not be forfeited
      during the Imminent Control Change Period, and will not continue to vest
      during the Imminent Control Change Period. If the Imminent Control Change
      lapses without a Change Date, such Performance Shares shall be governed
      according to the terms of the Exelon Corporation Key Management Severance
      Plan. If the Imminent Control Change Period culminates in a Change Date:

                        (1) All Performance Shares granted to the Executive
                  under the Exelon Performance Share Program under the LTIP,
                  which, as of the Termination Date, have been earned by and
                  awarded to the Executive, shall become fully vested at the
                  actual earned level on the Change Date, and

                        (2) All of the Performance Shares granted to the
                  Executive under the Exelon Performance Share Program under the
                  LTIP which, as of the Termination Date, have not been earned
                  by and awarded to the Executive shall become fully vested on
                  the Change Date at the LTIP Target Level.

            (e)   Termination During an Imminent Control Change Period:
      Restricted Stock.  Executive's unvested Restricted Stock will:

                  (i)   not be forfeited during the Imminent Control Change
            Period; and

                  (ii)  not continue to vest during the Imminent Control
            Change Period.

      If the Imminent Control Change Period lapses without a Change Date, such
      unvested Restricted Stock shall thereupon be forfeited.

            If the Imminent Control Change Period culminates in a Change Date,
      then immediately prior to the Change Date, Executive's Restricted Stock
      shall become fully vested, and within ten business days after the Change
      Date, the Company shall deliver to Executive all of such shares
      theretofore held by or on behalf of the Company, which will be subject to
      the same terms which other stockholders of the Company receive in the
      transaction.

            (f) Termination During an Imminent Control Change Period:
      Continuation of Welfare Benefits. The Company shall continue to provide to
      Executive and Executive's family welfare benefits (other than any
      severance pay that may be considered a welfare benefit) during the
      Imminent Change Period which are at least as favorable as welfare benefits
      under the most favorable Welfare Plans of the Company applicable with
      respect to peer executives who are actively employed after the Termination
      Date and their families; subject to the following:

                  (i) In determining benefits applicable under such Welfare
            Plans, the Executive's annual compensation attributable to base
            salary and incentives for any plan year or calendar year, as
            applicable, shall be deemed to be not less than the Executive's Base
            Salary and Annual Incentive;


                                       26
<PAGE>
                  (ii) The cost of such welfare benefits to Executive and family
            under this Section 4.2(f) shall not exceed the cost of such benefits
            to peer executives who are actively employed after the Termination
            Date.

                  (iii) Executive's rights under this Section 4.2(f) shall be in
            addition to and not in lieu of any post-termination continuation
            coverage or conversion rights the Executive may have pursuant to
            applicable law, including, without limitation, continuation coverage
            required by Section 4980B of the Code.

            If the Imminent Control Change Period lapses without a Change Date,
      welfare benefit plan coverage under this Section 4.2(f) shall thereupon
      cease, subject to Executive's rights, if any, to continued coverage under
      a Welfare Plan, the Exelon Corporation Key Management Severance Plan, or
      applicable law. If the Imminent Control Change Period culminates in a
      Change Date, then for the remainder of the Severance Period (and
      continuing through such later date as any Welfare Plan may specify), the
      Company shall continue to provide Executive and Executive's family welfare
      benefits as described in, and subject to the limitations of Section
      4.1(e).

      Notwithstanding the foregoing, if the Executive obtains a specific type of
coverage under welfare plan(s) sponsored by another employer of Executive (e.g.
medical, prescription, vision, dental, disability, individual life insurance
benefits, group life insurance benefits, but excluding for the purposes of this
sentence retiree benefits if Executive is so eligible), then the Company shall
not be obligated to provide such any specific type of coverage.

            (g) Termination During an Imminent Control Change Period:
      Outplacement. To the extent actually incurred by Executive, the Company
      shall pay or cause to be paid on behalf of Executive, as incurred, all
      reasonable fees and costs charged by a nationally recognized outplacement
      firm selected by the Executive for outplacement services provided up to 12
      months after the Termination Date. No cash shall be paid in lieu of such
      fees and costs.

            (h) Termination During an Imminent Control Change Period:
      Indemnification. The Executive shall be indemnified and held harmless by
      the Company to the same extent as provided in Section 4.1(g), but only
      during the Imminent Control Change Period (or greater period provided
      under the Company's by-laws) if the Imminent Control Change Period lapses
      without a Change Date.

            (i) Termination During an Imminent Control Change Period: Directors'
      and Officers' Liability Insurance. The Company shall provide the same
      level of directors' and officers' liability insurance for Executive as
      provided in Section 4.1(h), but only during the Imminent Control Change
      Period (or greater period provided under the Company's by-laws) if the
      Imminent Control Change Period lapses without a Change Date.

      4.3 Termination During a Post-Disaggregation Period. If, during a
Post-Disaggregation Period, the Disaggregated Entity terminates Executive's
employment other than for Cause or Disability, or if Executive terminates
employment for Good Reason, the Company's sole obligations to Executive under
Articles II and IV shall be as set forth in this Section 4.3, subject to Section
3.3(a)(iii), but only to the extent not provided by the Disaggregated Entity.


                                       27
<PAGE>
            (a)   Termination During a Post-Disaggregation Period:  Cash
      Severance Payments.  The Company shall pay Executive the amounts
      described in Section 4.1(a), as provided in Section 4.4.

            (b) Termination During a Post-Disaggregation Period: Stock Options.
      All of Executive's Stock Options granted that have not expired, whether or
      not converted to options or stock of the Disaggregated Entity or Merger
      Survivor, shall be fully vested, and may be exercised in whole or in part
      by the Executive at any time until (1) the remaining option expiration
      date for such Stock Options granted prior to January 1, 2002 and (2) the
      earlier of the fifth anniversary of the Termination Date or the option
      expiration date for such Stock Options granted on or after January 1,
      2002.

            (c) Termination During a Post-Disaggregation Period: Performance
      Shares. Executive's Performance Shares granted prior to the
      Disaggregation, whether or not earned by and awarded to the Executive as
      of the Disaggregation, and whether or not converted to performance shares
      of the Disaggregated Entity or the Merger Survivor, shall become fully
      vested (at the earned level for Performance Shares earned and awarded, and
      at the target level for any converted performance shares not yet earned
      and awarded) on the Termination Date.

            (d)   Termination During a Post-Disaggregation Period:
      Restricted Stock.  Executive's unvested Restricted Stock, whether or
      not converted to restricted stock of the Disaggregated Entity or Merger
      Survivor, shall become fully vested on the Termination Date.

            (e) Termination During a Post-Disaggregation Period: Continuation of
      Welfare Benefits. Until the end of the Severance Period, the Company shall
      continue to provide to Executive and Executive's family welfare benefits
      with the same rights in relation to continuation coverage, status in
      relation to other employer benefits, scope and cost as described in
      Section 4.1(e); provided that, to the extent Executive is eligible for
      post-termination continuation coverage under the plans of the
      Disaggregated Entity, whether pursuant to Section 4980B of the Code or
      otherwise, the continued coverage required hereunder shall be provided
      under the plans of the Disaggregated Entity (and the Company shall
      reimburse the cost to Executive of such coverage).

            (f) Termination During a Post-Disaggregation Period: Outplacement.
      To the extent actually incurred by Executive, the Company shall pay or
      cause to be paid on behalf of Executive, as incurred, all reasonable fees
      and costs charged by a nationally recognized outplacement firm selected by
      the Executive for outplacement services provided up to 12 months after the
      Termination Date. No cash shall be paid in lieu of such fees and costs.

            (g)   Termination During a Post-Disaggregation Period:
      Indemnification.  The Executive shall be indemnified and held harmless
      by the Company to the same extent as provided in Section 4.1(g).

      4.4 Timing of Severance Payments. Unless otherwise specified herein, the
amounts described in Sections 4.1(a)(i), (ii), (iii), (iv) and (v) shall be paid
within 30 business days of the Termination Date. The severance payments
described in Section 4.1(a)(vi) shall be paid as follows:

            (a) Beginning no later than the second paydate which occurs after
      the Termination Date, the Company shall make periodic payments to the
      Executive according to the Company's normal payroll practices at a monthly
      rate equal to 1/12 of the sum of (i) the Executive's Base Salary in effect
      as of the Termination Date plus (ii) the Severance Incentive; and

            (b) Within 30 business days of the second anniversary of the
      Termination Date, the Company shall pay Executive a cash lump sum equal to
      the difference between the total Severance Payment less the total amount
      paid pursuant to normal payroll practices under Section 4.4(a).

      4.5 Waiver and Release. Notwithstanding anything herein to the contrary,
the Company shall have no obligation to Executive under Article IV or Article V
unless and until Executive executes a release and waiver of Company and its
Affiliates, in substantially the same form as attached hereto as Exhibit A, or
as otherwise mutually acceptable.

      4.6 Breach of Covenants. If a court determines that Executive has breached
any non-competition, non-solicitation, confidential information or intellectual
property covenant entered into between Executive and Company, the Company shall
not be obligated to pay or provide any severance or benefits under Articles IV
or V, all unexercised Stock Options shall terminate as of the date of the
breach, and all Restricted Stock shall be forfeited as of the date of the
breach.

      4.7 Termination by the Company for Cause. If the Company (or Affiliate or,
if applicable, the Disaggregated Entity) terminates Executive's employment for
Cause during the Post-Change Period, the Imminent Control Change Period, the
Post-Significant Acquisition Period, or the Post-Disaggregation Period, the
Company's sole obligation to Executive under Articles II, IV, and V shall be to
pay Executive, pursuant to the Company's then-effective Plans, a lump-sum cash
amount equal to all Accrued Obligations determined as of the Termination Date.
The remaining applicable provisions of this Agreement (including the restrictive
covenants in Article IX) shall continue to apply.

      4.8 Termination by Executive Other Than for Good Reason. If Executive
elects to retire or otherwise terminate employment during the Post-Change
Period, the Imminent Control Change Period, the Post-Significant Acquisition
Period, or the Post-Disaggregation Period, other than for Good Reason,
Disability or death, the Company's sole obligation to Executive under Articles
II, IV, and V shall be to pay Executive, pursuant to the Company's
then-effective Plans, a lump-sum cash amount equal to all Accrued Obligations
determined as of the Termination Date. The remaining provisions of this
Agreement (including the restrictive covenants in Article IX) shall continue to
apply.

      4.9 Termination by the Company for Disability. If the Company (or
Disaggregated Entity, if applicable) terminates Executive's employment by reason
of Executive's Disability during the Post-Change Period, Imminent Control Change
Period that culminates in a Change Date, Post-Significant Acquisition Period or
Post-Disaggregation Period, the Company's sole


                                       29
<PAGE>
obligation to Executive under Articles II, IV, and V shall be as follows, and
such obligation shall be reduced by amounts paid or provided by the
Disaggregated Entity:

            (a) to pay Executive, a lump-sum cash amount equal to the sum of
      amounts specified in Section 4.1(a)(i), (ii) and (iii) determined as of
      the Termination Date, and

            (b) to provide Executive disability and other benefits after the
      Termination Date that are not less than the most favorable of such
      benefits then available under Plans of the Company to disabled peer
      executives of the Company in effect immediately before the Termination
      Date.

            The remaining provisions of this Agreement (including the
      restrictive covenants in Article IX) shall continue to apply.

      4.10 Upon Death. If Executive's employment is terminated by reason of
Executive's death during the Post-Change Period, Imminent Control Change Period
that culminates in a Change Date, Post-Significant Acquisition Period or
Post-Disaggregation Period, the Company's sole obligations to Executive and
Executive's Beneficiary under Articles II, IV, and V shall be as follows, and
such obligation shall be reduced by amounts paid or provided by the
Disaggregated Entity:

            (a)   to pay Executive's Beneficiary, pursuant to the Company's
      then-effective Plans, a lump-sum cash amount equal to all Accrued
      Obligations; and

            (b) to provide Executive's Beneficiary survivor and other benefits
      that are not less than the most favorable of such benefits then available
      under Plans of the Company to surviving families of peer executives of the
      Company in effect immediately before the Executive's death, [TAKING INTO
      ACCOUNT THE YEARS, IF ANY, OF CREDITED SERVICE GRANTED TO THE EXECUTIVE
      UNDER][CUSTOMIZE WITH SPECIFIC PROVISIONS FOR RETIREE/SURVIVOR COVERAGE.]

      4.11 Sole and Exclusive Obligations. The obligations of the Company under
this Agreement with respect to any Termination of Employment of the Executive
during the Post-Change Period, Imminent Control Change Period, Post-Significant
Acquisition Period, or Post-Disaggregation Period shall, except as provided in
Section 4.2, supersede any severance obligations of the Company in any other
Plan of the Company or agreement between Executive and the Company, including,
without limitations, the Exelon Corporation Key Management Severance Plan or any
other Plan or agreement (including an offer of employment or employment
contract) of the Company or any Affiliates which provides for severance
benefits. In the event of any inconsistency, ambiguity or conflict between the
terms of such other Plan of the Company or agreement between Executive and the
Company and this Agreement with respect to any severance obligations of the
Company (other than obligations with respect to credited service under the SERP
in any agreement), this Agreement shall govern.

                                   ARTICLE V.

                  CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

      5.1 Gross-Up Payment. If at any time or from time to time, it shall be
determined by the Company's independent auditors that any payment or other
benefit to Executive pursuant to Article II or Article IV of this Agreement or
otherwise ("Potential Parachute Payment") is or will become subject to the
excise tax imposed by Section 4999 of the Code or any similar tax payable under
any United States federal, state, local, foreign or other law ("Excise Taxes"),
then the Company shall, subject to Section 5.2, pay or cause to be paid a tax
gross-up payment ("Gross-Up Payment") with respect to all such Excise Taxes and
other Taxes on the Gross-Up Payment. The Gross-Up Payment shall be an amount
equal to the product of

            (a) The amount of the Excise Taxes (calculated at the effective
      marginal rates of all federal, state, local, foreign or other law),

      multiplied by

            (b) A fraction (the "Gross-Up Multiple"), the numerator or which is
      one (1.0), and the denominator of which is one (1.0) minus the lesser of
      (i) the sum, expressed as a decimal fraction, of the effective marginal
      rates of any Taxes and any Excise Taxes applicable to the Gross-Up Payment
      or (ii) .80, it being intended that the Gross-Up Multiple shall in no
      event exceed five (5.0). If different rates of tax are applicable to
      various portions of a Gross-Up Payment, the weighted average of such rates
      shall be used. For purposes of this Section, Executive shall be deemed to
      be subject to the highest effective marginal rate of Taxes.

The Gross-Up Payment is intended to compensate Executive for all such Excise
Taxes and any other Taxes payable by Executive with respect to the Gross-Up
Payment. The Company shall pay or cause to be paid the Gross-Up Payment to
Executive within thirty (30) days of the calculation of such amount, but in no
event after the Executive makes payment to the IRS of such Excise Taxes.

      5.2   Limitation on Gross-Up Payments.

            (a) To the extent possible, any payments or other benefits to
      Executive pursuant to Article II and Article IV of this Agreement shall be
      allocated as consideration for Executive's entry into the covenants of
      Article IX.

            (b) Notwithstanding any other provision of this Article V, if the
      aggregate amount of the Potential Parachute Payments that, but for this
      Section 5.2, would be payable to Executive, does not exceed 110% of Floor
      Amount (as defined below), then no Gross-Up Payment shall be made to
      Executive and the aggregate amount of Potential Parachute Payments payable
      to Executive shall be reduced (but not below the Floor Amount) to the
      largest amount which would both (i) not cause any Excise Tax to be payable
      by Executive and (ii) not cause any Potential Parachute Payments to become
      nondeductible by the Company by reason of Section 280G of the Code (or any
      successor provision). For purposes of the preceding sentence, "Floor
      Amount" means the greatest


                                       31
<PAGE>
      pre-tax amount of Potential Parachute Payments that could be paid to
      Executive without causing Executive to become liable for any Excise Taxes
      in connection therewith.

      5.3 Additional Gross-up Amounts. If, for any reason (whether pursuant to
subsequently enacted provisions of the Code, final regulations or published
rulings of the IRS, or a final judgment of a court of competent jurisdiction)
the Company's independent auditors later determine that the amount of Excise
Taxes payable by Executive is greater than the amount initially determined
pursuant to Section 5.1, then the Company shall, subject to Sections 5.2 and
5.4, pay Executive, within thirty (30) days of such determination, or pay to the
IRS as required by applicable law, an amount (which shall also be deemed a
Gross-Up Payment) equal to the product of:

            (a) the sum of (i) such additional Excise Taxes and (ii) any
      interest, penalties, expenses or other costs incurred by Executive as a
      result of having taken a position in accordance with a determination made
      pursuant to Section 5.1 or 5.4,

multiplied by

            (b)   the Gross-Up Multiple.

      5.4   Amount Increased or Contested.

            (a) Executive shall notify the Company in writing (an "Executive's
      Notice") of any claim by the IRS or other taxing authority (an "IRS
      Claim") that, if successful, would require the payment by Executive of
      Excise Taxes in respect of Potential Parachute Payments in an amount in
      excess of the amount of such Excise Taxes determined in accordance with
      Section 5.1. Executive's Notice shall include the nature and amount of
      such IRS Claim, the date on which such IRS Claim is due to be paid (the
      "IRS Claim Deadline"), and a copy of all notices and other documents or
      correspondence received by Executive in respect of such IRS Claim.
      Executive shall give the Executive's Notice as soon as practicable, but no
      later than the earlier of (i) 10 days after Executive first obtains actual
      knowledge of such IRS Claim or (ii) five days before the IRS Claim
      Deadline; provided, however, that any failure to give such Executive's
      Notice shall affect the Company's obligations under this Article only to
      the extent that the Company is actually prejudiced by such failure. If at
      least one business day before the IRS Claim Deadline the Company shall:

                  (i) deliver to Executive a written certificate from the
            Company's independent auditors ("Company Certificate") to the effect
            that, notwithstanding the IRS Claim, the amount of Excise Taxes,
            interest or penalties payable by Executive is either zero or an
            amount less than the amount specified in the IRS Claim,

                  (ii) pay to Executive, or to the IRS as required by applicable
            law, an amount (which shall also be deemed a Gross-Up Payment) equal
            to difference between the product of (A) amount of Excise Taxes,
            interest and penalties specified in the Company Certificate, if any,
            multiplied by (B) the Gross-Up Multiple, less the portion of such
            product, if any, previously paid to Executive by the Company, and


                                       32
<PAGE>
                  (iii) direct Executive pursuant to Section 5.4(d) to
            contest the balance of the IRS Claim,

      then Executive shall pay only the amount, if any, of Excise Taxes,
      interest and penalties specified in the Company Certificate. In no event
      shall Executive pay an IRS Claim earlier than 30 business days after
      having given an Executive's Notice to the Company (or, if sooner, the IRS
      Claim Deadline).

            (b) At any time after the payment by Executive of any amount of
      Excise Taxes, other Taxes or related interest or penalties in respect of
      Potential Parachute Payments (including any such amount equal to or less
      than the amount of such Excise Taxes specified in any Company Certificate,
      or IRS Claim), the Company may in its discretion require Executive to
      pursue a claim for a refund (a "Refund Claim") of all or any portion of
      such Excise Taxes, other Taxes, interest or penalties as may be specified
      by the Company in a written notice to Executive.

            (c) If the Company notifies Executive in writing that the Company
      desires Executive to contest an IRS Claim or to pursue a Refund Claim,
      Executive shall:

                  (i) give the Company all information that it reasonably
            requests in writing from time to time relating to such IRS Claim or
            Refund Claim, as applicable,

                  (ii) take such action in connection with such IRS Claim or
            Refund Claim (as applicable) as the Company reasonably requests in
            writing from time to time, including accepting legal representation
            with respect thereto by an attorney selected by the Company, subject
            to the approval of Executive (which approval shall not be
            unreasonably withheld or delayed),

                  (iii) cooperate with the Company in good faith to contest such
            IRS Claim or pursue such Refund Claim, as applicable,

                  (iv)  permit the Company to participate in any proceedings
            relating to such IRS Claim or Refund Claim, as applicable, and

                  (v) contest such IRS Claim or prosecute Refund Claim (as
            applicable) to a determination before any administrative tribunal,
            in a court of initial jurisdiction and in one or more appellate
            courts, as the Company may from time to time determine in its
            discretion.

      The Company shall control all proceedings in connection with such IRS
      Claim or Refund Claim (as applicable) and in its discretion may cause
      Executive to pursue or forego any and all administrative appeals,
      proceedings, hearings and conferences with the Internal Revenue Service or
      other taxing authority in respect of such IRS Claim or Refund Claim (as
      applicable); provided that (i) any extension of the statute of limitations
      relating to payment of taxes for the taxable year of Executive relating to
      the IRS Claim is limited solely to such IRS Claim, (ii) the Company's
      control of the IRS Claim or Refund Claim (as applicable) shall be limited
      to issues with respect to which a Gross-Up Payment


                                       33
<PAGE>
      would be payable, and (iii) Executive shall be entitled to settle or
      contest, as the case may be, any other issue raised by the Internal
      Revenue Service or other taxing authority.

            (d) The Company may at any time in its discretion direct Executive
      to (i) contest the IRS Claim in any lawful manner or (ii) pay the amount
      specified in an IRS Claim and pursue a Refund Claim; provided, however,
      that if the Company directs Executive to pay an IRS Claim and pursue a
      Refund Claim, the Company shall advance the amount of such payment to
      Executive on an interest-free basis and shall indemnify Executive, on an
      after-tax basis, for any Excise Tax or income tax, including related
      interest or penalties, imposed with respect to such advance.

            (e) The Company shall pay directly all legal, accounting and other
      costs and expenses (including additional interest and penalties) incurred
      by the Company or Executive in connection with any IRS Claim or Refund
      Claim, as applicable, and shall indemnify Executive, on an after-tax
      basis, for any Excise Tax or income tax, including related interest and
      penalties, imposed as a result of such payment of costs and expenses.

      5.5 Refunds. If, after the receipt by Executive or the IRS of any payment
or advance of Excise Taxes or other Taxes by the Company pursuant to this
Article, Executive receives any refund with respect to such Excise Taxes,
Executive shall (subject to the Company's complying with any applicable
requirements of Section 5.4) promptly pay the Company the amount of such refund
(together with any interest paid or credited thereon after taxes applicable
thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 5.4 or receipt by the IRS of an amount paid by the
Company on behalf of the Executive pursuant to Section 5.4, a determination is
made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to
contest such determination within 30 days after the Company receives written
notice of such determination, then such advance shall be forgiven and shall not
be required to be repaid and the amount of such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid. Any contest
of a denial of refund shall be controlled by Section 5.4(d).

                                   ARTICLE VI.

                  EXPENSES, INTEREST AND DISPUTE RESOLUTION

      6.1   Enforcement and Late Payments.

            (a) If, after the Agreement Date, Executive incurs reasonable legal
      fees or other expenses (including arbitration costs and expenses under
      Section 6.3) in an effort to secure, preserve, or obtain benefits under
      this Agreement, the Company shall, regardless of the outcome of such
      effort, reimburse Executive (in accordance with Section 6.1(b)) for such
      fees and expenses.

            (b) Reimbursement of legal fees and expenses and gross-up payments
      shall be made on a current basis, promptly after Executive's written
      submission of a request for reimbursement together with evidence that such
      fees and expenses were incurred.

            (c) If Executive does not prevail (after exhaustion of all available
      judicial remedies) in respect of a claim by Executive or by the Company
      hereunder, and the


                                       34
<PAGE>
      Company establishes before a court of competent jurisdiction by clear and
      convincing evidence that Executive had no reasonable basis for Executive's
      claim hereunder, or for Executive's response to the Company's claim
      hereunder, or that Executive acted in bad faith, no further reimbursement
      for legal fees and expenses shall be due to Executive in respect of such
      claim and Executive shall refund any amounts previously reimbursed
      hereunder with respect to such claim.

      6.2 Interest. If the Company does not pay any cash amount due to Executive
under this Agreement within three business days after such amount first became
due and owing, interest shall accrue on such amount from the date it became due
and owing until the date of payment at an annual rate equal to 200 basis points
above the base commercial lending rate published in The Wall Street Journal in
effect from time to time during the period of such nonpayment; provided that the
Executive shall not be entitled to interest on any Gross-Up Payment.

      6.3 Arbitration. Any dispute, controversy or claim between the parties
hereto arising out of or in connection with or relating to this Agreement (other
than disputes related to Article V or to an alleged breach of the covenant
contained in Article IX) or any breach or alleged breach thereof, or any benefit
or alleged benefit hereunder, shall be settled by arbitration in Chicago,
Illinois, before an impartial arbitrator pursuant to the rules and regulations
of the American Arbitration Association ("AAA") pertaining to the arbitration of
labor disputes. Either party may invoke the right to arbitration. The arbitrator
shall be selected by means of the parties striking alternatively from a panel of
seven arbitrators supplied by the Chicago office of AAA. The arbitrator shall
have the authority to interpret and apply the provisions of this Agreement,
consistent with Section 11.11 below. The decision of the arbitrator shall be
final and binding upon the parties and a judgment thereon may be entered in the
highest court of a forum, state or federal, having jurisdiction. The expenses of
the arbitration shall be borne according to Section 6.1. No arbitration shall be
commenced after the date when institution of legal or equitable proceedings
based upon such subject matter would be barred by the applicable statutes of
limitations. Notwithstanding anything to the contrary contained in this Section
6.3 or elsewhere in this Agreement, either party may bring an action in the
District Court of Cook County, or the United States District Court for the
Northern District of Illinois, if jurisdiction there lies, in order to maintain
the status quo ante of the parties. The "status quo ante" is defined as the last
peaceable, uncontested status between the parties. However, neither the party
bringing the action nor the party defending the action thereby waives its right
to arbitration of any dispute, controversy or claim arising out of or in
connection or relating to this Agreement. Notwithstanding anything to the
contrary contained in this Section 6.3 or elsewhere in this Agreement, either
party may seek relief in the form of specific performance, injunctive or other
equitable relief in order to enforce the decision of the arbitrator. The parties
agree that in any arbitration commenced pursuant to this Agreement, the parties
shall be entitled to such discovery (including depositions, requests for the
production of documents and interrogatories) as would be available in a federal
district court pursuant to Rules 26 through 37 of the Federal Rules of Civil
Procedure. In the event that either party fails to comply with its discovery
obligations hereunder, the arbitrator shall have full power and authority to
compel disclosure or impose sanctions to the full extent of Rule 37 of the
Federal Rules of Civil Procedure.

                                  ARTICLE VII.

                  NO ADVERSE EFFECT ON POOLING OF INTERESTS

      Any benefits provided to the Executive under this Agreement may be reduced
or eliminated to the extent necessary, in the reasonable judgment of the Board,
to enable the Company to account for a merger, consolidation or similar
transaction as a pooling of interests; provided that (i) the Board shall have
exercised such judgment and given the Executive written notice thereof prior to
the Change Date and (ii) the determination of the Board shall be supported by a
written certificate of the Company's independent auditors, a copy of which shall
be provided to the Executive before the Change Date.

                                  ARTICLE VIII.

                            NO SET-OFF OR MITIGATION

      8.1 No Set-off by Company. Executive's right to receive when due the
payments and other benefits provided for under this Agreement is absolute,
unconditional and subject to no setoff, counterclaim or legal or equitable
defense. Time is of the essence in the performance by the Company of its
obligations under this Agreement. Any claim which the Company may have against
Executive, whether for a breach of this Agreement or otherwise, shall be brought
in a separate action or proceeding and not as part of any action or proceeding
brought by Executive to enforce any rights against the Company under this
Agreement.

      8.2 No Mitigation. Executive shall not have any duty to mitigate the
amounts payable by the Company under this Agreement by seeking new employment or
self-employment following termination. Except as specifically otherwise provided
in this Agreement, all amounts payable pursuant to this Agreement shall be paid
without reduction regardless of any amounts of salary, compensation or other
amounts which may be paid or payable to Executive as the result of Executive's
employment by another employer or self-employment.

                                   ARTICLE IX.

                              RESTRICTIVE COVENANTS

      9.1 Confidential Information. The Executive acknowledges that in the
course of performing services for the Companies and Affiliates, he may create
(alone or with others), will have or will learn of, have access to and receive
Confidential Information. Confidential Information shall not include: (i)
information that is or becomes generally known through no fault of Executive;
(ii) information received from a third party outside of the Company that was
disclosed without a breach of any confidentiality obligation; or (iii)
information approved for release by written authorization of the Company. The
Executive recognizes that all such Confidential Information is the sole and
exclusive property of the Company and its Affiliates or of third parties which
the Company or Affiliate is obligated to keep confidential, that it is the
Company's policy to keep all such Confidential Information confidential, and
that disclosure of Confidential Information would cause damage to the Company
and its Affiliates. The Executive agrees that, except as required by the duties
of Executive's employment with the Company or any of its Affiliates and except
in connection with enforcing the Executive's rights under this


                                       36
<PAGE>
Agreement or if compelled by a court or governmental agency, in each case
provided that prior written notice is given to Company, Executive will not,
without the consent of Company, willfully disseminate or otherwise disclose,
directly or indirectly, any Confidential Information obtained during his
employment with the Company or its Affiliates, and will take all necessary
precautions to prevent disclosure, to any unauthorized individual or entity
inside or outside the Company, and will not use the Confidential Information or
permit its use for the benefit of Executive or any other person or entity other
than the Company or its Affiliates. These obligations shall continue during and
after the termination of Executive's employment (whether or not after a Change
in Control, Imminent Control Change, Significant Acquisition or Disaggregation).

      9.2 Non-Competition. During the period beginning on the Agreement Date and
ending on the second anniversary of the Termination Date, whether or not after a
Change in Control, Imminent Control Change, Significant Acquisition or
Disaggregation, Executive hereby agrees that without the written consent of the
Company Executive shall not at any time, directly or indirectly, in any
capacity:

            (a) engage or participate in, become employed by, serve as a
      director of, or render advisory or consulting or other services in
      connection with, any Competitive Business; provided, however, that after
      the Termination Date this Section 9.2 shall not preclude Executive from
      being an employee of, or consultant to, any business unit of a Competitive
      Business if (i) such business unit does not qualify as a Competitive
      Business in its own right and (ii) Executive does not have any direct or
      indirect involvement in, or responsibility for, any operations of such
      Competitive Business that cause it to qualify as a Competitive Business.

            (b) make or retain any financial investment, whether in the form of
      equity or debt, or own any interest, in any Competitive Business. Nothing
      in this subsection shall, however, restrict Executive from making an
      investment in any Competitive Business if such investment does not (i)
      represent more than 1% of the aggregate market value of the outstanding
      capital stock or debt (as applicable) of such Competitive Business, (ii)
      give Executive any right or ability, directly or indirectly, to control or
      influence the policy decisions or management of such Competitive Business,
      and (iii) create a conflict of interest between Executive's duties under
      this Agreement and his interest in such investment.

      9.3 Non-Solicitation. During the period beginning on the Agreement Date
and ending on the second anniversary of any Termination Date, whether or not
after a Change in Control, Imminent Control Change, Significant Acquisition or
Disaggregation, Executive shall not, directly or indirectly:

            (a) other than in connection with the good-faith performance of his
      duties as an officer of the Company, cause or attempt to cause any
      employee or agent of the Company to terminate his or her relationship with
      the Company;

            (b) employ, engage as a consultant or adviser, or solicit the
      employment or engagement as a consultant or adviser, of any employee or
      agent of the Company (other than by the Company or its Affiliates), or
      cause or attempt or cause any Person to do any of the foregoing;


                                       37
<PAGE>
            (c) establish (or take preliminary steps to establish) a business
      with, or cause or attempt to cause others to establish (or take
      preliminary steps to establish) a business with, any employee or agent of
      the Company, if such business is or will be a Competitive Business; or

            (d) interfere with the relationship of the Company with, or endeavor
      to entice away from the Company, any Person who or which at any time
      during the period commencing one year prior to the Termination Date was or
      is, to the Executive's knowledge, a material customer or material supplier
      of, or maintained a material business relationship with, the Company.

      9.4 Intellectual Property. During the period of Executive's employment
with the Company or any Affiliate, and thereafter upon the Company's request,
whether or not after a Change in Control, Imminent Control Change, Significant
Acquisition or Disaggregation, Executive shall disclose immediately to the
Company all ideas, inventions and business plans that he makes, conceives,
discovers or develops alone or with others during the course of his employment
with the Company or during the one year period following Executive's Termination
Date, including any inventions, modifications, discoveries, developments,
improvements, computer programs, processes, products or procedures (whether or
not protectable upon application by copyright, patent, trademark, trade secret
or other proprietary rights) ("Work Product") that: (i) relate to the business
of the Company or any customer or supplier to the Company or any of the products
or services being developed, manufactured, sold or otherwise provided by the
Company or that may be used in relation therewith; or (ii) result from tasks
assigned to Executive by the Company; or (iii) result from the use of the
premises or personal property (whether tangible or intangible) owned, leased or
contracted for by the Company. Executive agrees that any Work Product shall be
the property of the Company and, if subject to copyright, shall be considered a
"work made for hire" within the meaning of the Copyright Act of 1976, as amended
(the "Act"). If and to the extent that any such Work Product is not a "work made
for hire" within the meaning of the Act, Executive hereby assigns to the Company
all right, title and interest in and to the Work Product, and all copies
thereof, and the copyright, patent, trademark, trade secret and all proprietary
rights in the Work Product, without further consideration, free from any claim,
lien for balance due or rights of retention thereto on the part of Executive.

            (a) The Company hereby notifies Executive that the preceding
      paragraph does not apply to any inventions for which no equipment,
      supplies, facility, or trade secret information of the Company was used
      and which was developed entirely on the Executive's own time, unless: (i)
      the invention relates (a) to the Company's business, or (b) to the
      Company's actual or demonstrably anticipated research or development, or
      (ii) the invention results from any work performed by the Executive for
      the Company.

            (b) Executive agrees that upon disclosure of Work Product to the
      Company, Executive will, during his employment and at any time thereafter,
      at the request and cost of the Company, execute all such documents and
      perform all such acts as the Company or its duly authorized agents may
      reasonably require: (i) to apply for, obtain and vest in the name of the
      Company alone (unless the Company otherwise directs) letters patent,
      copyrights or other analogous protection in any country throughout the
      world, and when so obtained or vested to renew and restore the same; and
      (ii) to prosecute or defend any opposition proceedings in respect of such
      applications and any opposition proceedings or


                                       38
<PAGE>
      petitions or applications for revocation of such letters patent, copyright
      or other analogous protection, or otherwise in respect of the Work
      Product.

            (c) In the event that the Company is unable, after reasonable
      effort, to secure Executive's execution as provided in subsection (b)
      above, whether because of Executive's physical or mental incapacity or for
      any other reason whatsoever, Executive hereby irrevocably designates and
      appoints the Company and its duly authorized officers and agents as his
      agent and attorney-in-fact, to act for and on his behalf to execute and
      file any such application or applications and to do all other lawfully
      permitted acts to further the prosecution, issuance and protection of
      letters patent, copyright and other intellectual property protection with
      the same legal force and effect as if personally executed by Executive.

      9.5   Reasonableness of Restrictive Covenants.

            (a) Executive acknowledges that the covenants contained in Sections
      9.1, 9.2, 9.3 and 9.4 are reasonable in the scope of the activities
      restricted, the geographic area covered by the restrictions, and the
      duration of the restrictions, and that such covenants are reasonably
      necessary to protect the Company's legitimate interests in its
      Confidential Information and in its relationships with its employees,
      customers and suppliers. Executive further acknowledges such covenants are
      essential elements of this Agreement and that, but for such covenants, the
      Company would not have entered into this Agreement.

            (b) The Company and Executive have each consulted with their
      respective legal counsel and have been advised concerning the
      reasonableness and propriety of such covenants. Executive acknowledges
      that his observance of the covenants contained in Sections 9.1, 9.2, 9.3
      and 9.4 will not deprive Executive of the ability to earn a livelihood or
      to support his dependents.

      9.6   Right to Injunction; Survival of Undertakings.

            (a) In recognition of the confidential nature of the Confidential
      Information, and in recognition of the necessity of the limited
      restrictions imposed by Sections 9.1, 9.2, 9.3 and 9.4 the parties agree
      that it would be impossible to measure solely in money the damages which
      the Company would suffer if Executive were to breach any of his
      obligations under such Sections. Executive acknowledges that any breach of
      any provision of such Sections would irreparably injure the Company.
      Accordingly, Executive agrees that if he breaches any of the provisions of
      such Sections, the Company shall be entitled, in addition to any other
      remedies to which the Company may be entitled under this Agreement or
      otherwise, to an injunction to be issued by a court of competent
      jurisdiction, to restrain any breach, or threatened breach, of such
      provisions, and Executive hereby waives any right to assert any claim or
      defense that the Company has an adequate remedy at law for any such
      breach.

            (b) If a court determines that any of the covenants included in this
      Article IX is unenforceable in whole or in part because of such covenant's
      duration or geographical or other scope, such court shall have the power
      to modify the duration or scope of such


                                       39
<PAGE>
      provision, as the case may be, so as to cause such covenant as so modified
      to be enforceable.

            (c) All of the provisions of this Article IX shall survive any
      Termination of Employment without regard to (i) the reasons for such
      termination or (ii) the expiration of the Agreement Term.

            (d) The Company shall have no further obligation to pay or provide
      severance or benefits under Article II, Article IV, or Article V if a
      court determines that the Executive has breached any covenant in this
      Article IX.

                                   ARTICLE X.

                            NON-EXCLUSIVITY OF RIGHTS

      10.1 Other Rights. Except as expressly provided in Section 4.11 or
elsewhere in this Agreement, this Agreement shall not prevent or limit
Executive's continuing or future participation in any benefit, bonus, incentive
or other Plans provided by the Company and for which Executive may qualify, nor
shall this Agreement limit or otherwise affect such rights as Executive may have
under any other agreements with the Company. Amounts which are vested benefits
or which Executive is otherwise entitled to receive under any Plan and any other
payment or benefit required by law at or after the Termination Date shall be
payable in accordance with such Plan or applicable law except as expressly
modified by this Agreement.

      10.2 No Right to Continued Employment. Nothing in this Agreement shall
guarantee the right of Executive to continue in employment, and the Company
retains the right to terminate the Executive's employment at any time for any
reason or for no reason.

                                   ARTICLE XI.

                                  MISCELLANEOUS

      11.1 No Assignability. This Agreement is personal to Executive and without
the prior written consent of the Company shall not be assignable by Executive
otherwise than by will or the laws of descent and distribution. This Agreement
shall inure to the benefit of and be enforceable by Executive's legal
representatives.

      11.2 Successors. This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns. The Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to assume expressly and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Any successor to the business
or assets of the Company which assumes or agrees to perform this Agreement by
operation of law, contract, or otherwise shall be jointly and severally liable
with the Company under this Agreement as if such successor were the Company.

      11.3 Affiliates. To the extent that immediately prior to the Applicable
Trigger Date, the Executive has been on the payroll of, and participated in the
incentive or employee benefit


                                       40

plans of, an Affiliate of the Company, the references to the Company contained
in Sections 2.9(a)(i) through (vi) and the other Sections of this Agreement
referring to benefits to which the Executive may be entitled shall be read to
refer to such Affiliate.

      11.4 Payments to Beneficiary. If Executive dies before receiving amounts
to which Executive is entitled under this Agreement, such amounts shall be paid
in a lump sum to one or more beneficiaries designated in writing by Executive
(each, a "Beneficiary"). If none is so designated, the Executive's estate shall
be his or her Beneficiary.

      11.5 Non-Alienation of Benefits. Benefits payable under this Agreement
shall not be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, charge, garnishment, execution or levy of any
kind, either voluntary or involuntary, before actually being received by
Executive, and any such attempt to dispose of any right to benefits payable
under this Agreement shall be void.

      11.6 Severability. If any one or more Articles, Sections or other portions
of this Agreement are declared by any court or governmental authority to be
unlawful or invalid, such unlawfulness or invalidity shall not serve to
invalidate any Article, Section or other portion not so declared to be unlawful
or invalid. Any Article, Section or other portion so declared to be unlawful or
invalid shall be construed so as to effectuate the terms of such Article,
Section or other portion to the fullest extent possible while remaining lawful
and valid.

      11.7  Amendments.  This Agreement shall not be amended or modified
except by written instrument executed by the Company and Executive.
